Have you ever wondered where you can buy the cheapest petrol or groceries? Well, if you have, then you would know that such information is not readily available.

Remember the timing? Mark Knight of the Herald Sun / File

You may try and search for the information, but in Australia you will soon find that there is generally no single place to get it. Yes, there may be some pricing information out there but it may be very limited, out of date or not in a readily accessible form.

In practice, this lack of full price transparency places you, the consumer, at a severe disadvantage. How many times have you driven by a petrol station offering one price only to find another service station down the road offering a cheaper price? What if you had decided to go into the first service station to buy your petrol only to later drive by the cheaper service station down the road? We have all been there and felt ripped off in the process.

On those occasions you have been the victim of what the economists call “information asymmetries.” That’s where the supplier of the product or service has more information at its fingertips than do consumers.

Take the petrol station example. Petrol Company A will know that in location 1 there is less competition so it can charge a higher price for petrol. In fact, the petrol company will know the price in near real time at all its service stations, as well as the price charged by its competitors.

The motorist, however, only has part of the picture. Motorists need to rely on their own “searches” such as when they drive by petrol stations or where they check an online service such as motormouth.com.au which provides limited and potentially out of date pricing information.

For the motorist these “searches” are far from perfect. Such “searches” are time consuming and ultimately futile as the searches are limited by time and place and prices can and do change in real time. In short, the information available to the motorists from the “searches” can very quickly get out of date.

Compare this to the pricing information available to the petrol companies and other petrol retailers such as Coles and Woolworths.

First, the major petrol retailers know the price at all their service stations in real time or near real time. Either they set the price or that information is available electronically as petrol transactions are tracked and that information is transmitted back to corporate HQ and to service providers such as a company called “Informed Sources.”

That brings us to the other part of the picture where the major petrol retailers know the price at their competitors service stations in real time or near real time. That’s where “Informed Sources” comes in. Informed Sources will collect and disseminate price information to its subscribers in near real time. That’s how the petrol companies and other major retailers know what their competitors charge and can respond accordingly. That pricing information allows the petrol retailers to charge different prices at different locations, a practice previously discussed and known as “geographic price discrimination.”

The problem is that motorists don’t know the prices at different service stations as quickly or as comprehensively as do the petrol retailers.

The answer? Simple, either petrol retailers make available online and in real time the prices at all their services stations, or the pricing information held by Informed Sources is also made available to motorists. Those simple suggestions would go all or almost all of the way to removing the information asymmetries faced by motorists that prevent them from identifying the cheapest petrol prices.

Sounds easy doesn’t it? Pricing information is already available to the petrol companies so it’s only a small step to provide it to motorists.

As for the cost of doing so, well, the electronic age in which we are living means that the cost of providing that information is miniscule in the scheme of things.

Or, as the economists would say the “marginal cost” of providing the information is near zero as the pricing information is automatically and electronically updated anyway for corporate accounting and reporting purposes.

The same goes for groceries. In Australia there is nothing that gives anything approaching full price transparency. Woolworths has a few thousand products online but the information is only for a fraction of the upwards of 30,000 products typically sold at a Woolworths supermarket. Worse for consumers the pricing information is updated only once a week.

The Woolworths “price check” website even states that if the standard shelf price changes during the week, the new shelf price on the website will only be updated the following Monday.

Yes, there is information online regarding weekly specials, but of course they would advertise those. What about the thousands of other products sold at a Woolworths? And, what about Coles? Well, Coles is still playing catch up and trails Woolworths on the provision of pricing information.

Why is it important to get full pricing transparency from Woolworths and Coles? Simply because Woolworths and Coles may still charge different prices for the same product in their respective stores in the same geographic area. The only way that consumers can ever know where to find the cheapest price for a particular product is to conduct their own “searches.” And, we know how futile they can be!

This is just another example of where Australian consumers are well and truly behind their overseas cousins. Not only do Australian consumers consistently face some of the highest levels of food inflation in the developed world, but just have a look at the mySupermarket website available to United Kingdom consumers.

Consumers in the UK have access to pricing information that Australian consumers can only dream about. The answer? Simple, either Woolworths and Coles make available online and in real time the prices of all the products sold at all their supermarkets or they make available their pricing information to a third party that can create an Australian version of the UK mySupermarket website.

So, with Australian consumers still the ongoing victims of “information asymmetries” you would think that the Federal Government would do something about it.

Yes, promises were made about petrol and grocery prices before the last Federal election by the then Labor Opposition. All we got after the election were the failed Fuelwatch and GroceryChoice schemes neither of which provided the real time information that’s so important to empower consumers.

With a new election around the corner will we see some new “promises” or will silence be golden?

      Speak for yourself. Really what’s the difference between two stations in the same area. Tenths of a cent usually but let’s say it was one cent.. On a full refill that’s 60 cents difference. You’ll have to forgive me if I don’t actually lose any sleep over paying $81.60 instead of a neat $81.00 for a tank of gas.

      Woolworths and Coles may still charge different prices for the same product in their respective stores in the same geographic area.

      Yeah! Let’s drive 5kms to save ten cents on a loaf of bread. I remember when there was a regular grocery price check in Newcastle. They would price a basket of goods at around 30 different supermarkets. The difference between the cheapest and dearest major supermarkets was 1 or 2%. That means on a $200 grocery bill you may save $4 if you drove to the cheapest one. I wonder how far the average person would drive to save $4?

      Once again I ask if the big grocery and petrol companies are ripping us off so much then where are the independents doing it cheaper? Or what about the global big boys? Where’s Tesco, Sainburys or Carrefour? If there were big margins available in the Australian Grocery market don’t you think they’d be here?

      I agree on the sums.  The real difference is so small that you can almost spend more travelling to save the money.  What people resent is the arbitrariness of it all.  The variations appear to be designed for one thing - ripping people off because the retailers can and not because of any real variation in input costs.

      Bought petrol today in Perth. Looked at http://www.fuelwatch.com.au/ before I left.  I Paid 117.9 (no discount) on the way to the station I bought the petrol at I passed a BP selling the same grade of petrol at 133.9, ... In case you have trouble with the sums, that is 16 cents per litre less… IF you have a big tank, that is a sizable savings.

      I work on the premise that if industry can profit from something they will do it. We simply don’t have the infrastructure to support every car in Sydney going to the one cheap petrol station, or the one decent supermarket. It is local rules, and in that circumstance, the local search is better than the global one. Rudd’s various watch schemes failed because of this.

    • Aberford says:

      Sherlock, you’re missing the point.

      Your clever reference to tenths of a cent is a diversion, perhaps inadvertently, from what Frank Zumbo is saying.

      He makes the point that the corporates have realtime info about market pricing, and consumers do not, so the corporates can, and do, use this advantage to play consumers like trout.

      The supermarkets do it to some extent, but as usual the worst offenders are the oil majors, where price changes can be not tenths of a cent but ten cents, and in the blink of an eye at the same servo.

      Despite the fact that they do this with the beaming approval of the ACCC, there are no shortterm “market forces” involved, as global oil prices do not magically shoot up every Friday and down every Wednesday (Graeme Samuel please note).

      And your point about competing with the oil oligopoly is a joke to anyone with the slightest knowledge of how the industry deals with that.

      Prices sometimes do change fairly dynamically.  I have seen petrol prices change as I pass or enter a petrol station.  Sometimes at supermarkets and department stores an old price tag is overlooked and you find you are charged a different price at checkout.  I can imagine that with 30,000 items a supermarket does not always keep completely up-to-date tabs on each item.  And it is clear that supermarkets price the same goods differently in their own stores in different locations and can have price wars with competing supermarkets and smaller shops in a given location.
      I think one (not fool-proof) way of addressing this situation is to set up a daily blog (entries older than 24 hours are dropped unless prices are guaranteed for a few days) where members of the public can report the prices they have seen or purchased at, whether it is petrol or vegetables or fruit or even white goods and hi-fi equipment.  People can then decide whether it is worth their effort to travel to a particular place to purchase something at a particular price.  Retailers may want to update the blog themselves to advertise their specials! Choice might be a good organisation to host this kind of blog (or blogs – for different kinds of goods).

      John G W If the item you take to the checkout has a different price from the one you are charged, demand it be sold to you at the ticketed price. Some stores give you the item for free.

      What I really want to know is why diesel is more expensive than standard unleaded by 10c a litre or more on a regular basis.  And don’t give me that rubbish about supply and demand, I have never seen a petrol station “out of diesel”. With more manufacturers embracing diesel (as a step towards cleaner fuels - bring on hydrogen!!), the less refined diesel should be just as abundant as the more refined unleaded (and premium, ethanol enhanced, etc).  Why the big price difference?

      You can find the cheapest petrol in Perth very easily.

      It’s right here
      http://www.fuelwatch.com.au/

      Couldn’t believe when the Liberal morons shot this own a few years ago. Works a treat.

    • Shifter says:

      12:08pm | 08/07/10

      The only reason that works is WA has set petrol pricing in a 24 hour period. The servos can’t dynamically change their prices over a day as I believe still happens in other states (correct me if I am wrong).

      From my perspective, the best thing on the WA fuelwatch site is you are informed of the coming day’s price the previous evening, which makes it easy to gauge whether it is cheaper to fill up now, or the next day.

      The worst thing? Hasn’t done a thing to stop petrol price inflation.

    • The Badger says:

      01:05pm | 08/07/10

      You are right about the WA set petrol price Shifter and I believe other states can change the price anytime they like.

      This morning I saved 16 cents a litre. (117.8 vs 133.9 at a BP I passed along the way). This does make a difference when you have a 150 litre tank like I do. That was a saving of $24.00

      Failing that, two simple rules for 90% of the time in Perth:
      1. Go on Wednesday (sometimes Thursday, but this is riskier)
      2. Boycott Profiteering (read the abbreviations to find which station I’m primarily talking about. Hint: They always lead the cycle on Wednesday)

      Labor and Liberal have no interest in keeping the big supermarkets honest. The sooner the grocery council wakes up to this the better Australians will be.

      Being in WA where my husband and I both work full time and can only shop for a few hours each week out of working hours, I would never use a grocery comparision site. How much of a saving would I have to achieve to take 30 mins of my time searching the web for what I planned to buy (this assumes I plan each purchase before I walk into the supermarket) and extra travel time and petrol…? I reckon even $20 or $30 a go wouldn’t make much difference to me over the conveinience of going to my local supermarket where I know where everything is and can race around the shelves and do the week’s grocery shopping in 30 mins!

      Same with Petrol. I have fuel watch but I don’t use it. I know which servos tend to be the cheapest ones and I avoid the ones I know are always expensive. Sometimes I save, sometimes I don’t but I don’t really care.

      07:31pm | 08/07/10

      I’m in Perth and use http://www.fuelwatch.wa.gov.au every week.

      Whether Perth petrol prices are cheaper than in other states or not (I believe the ACCC found Perth prices WERE cheaper), the fact that I can save money on the day, and don’t need to go chasing past stations means I’m a happy camper!
