Every few years the Australian Consumers Association dusts off its tattered old file about unit pricing, puts out a news release, runs a post on its website, paints out the name of the politician who was minister for consumer affairs three years ago and updates the letter. There’s a flurry and it all goes away until next time.
Because every time the proposal has been looked at, people have noticed it flies like an iron kite.
There is no clear benefit for consumers in general or even those consumers for whom price is an over-riding consideration.
“Unit pricing” means that for every product line there would be two shelf prices: the price for the pack and the price (for example) per kilogram or litre.
All of that - across the 25,000 product lines in a large supermarket - would require a lot more management of price changes and shelf-labelling. And benefit how many customers, exactly? Once the ACA staff have done their weekly shopping, not many.
And thus unit pricing would come at an additional cost - all of which would be passed on in the shelf price to all customers, not just those who want unit pricing. Nobody has demonstrated that the increased costs are offset by the benefit of satisfying the unproven consumer desire to know the comparative price per unit.
Nor does unit pricing help compare the price of the store-brand frozen prawns from Thailand (which are vile, anyway) with the fresh prawns from Queensland. Nor the store-brand item from Uganda with the competing store-brand from Ecuador. Does the unit price gimmick off-set the commendable patriotic desire to support local producers and jobs by buying “Product of Australia”? Probably not.
Unit pricing is supposed to give more information to consumers - whether they want it or not. But when is the last time you heard somebody bewailing the lack of unit pricing?
This is how it is promoted by ACA: people are confused by prices for different pack sizes. Somebody should so something! Somebody should legislate! ACA is not put off by the mere fact that the vast majority of grocery shoppers don’t give a toss. The editors of Choice magazine know what’s best for those dumb shoppers.
For the record, customer demand for this sort of information falls on a scale somewhere between neglible and zero. And customers are not shy about telling supermarket operators what they want when it’s a subject they care about.
The ACA asks us to believe customers are “confused” by the absence of unit pricing; the Sydney Morning Herald says customers are “baffled”: does the 375g pack or the 600gm pack give better value? Decisions, decisions, decisions. A customer would be able to work it out if only the unit price were on the shelf.
Neither of these venerable publications actually produced a statistically valid sample to support the proposal.
Do people really lie awake at night in a sweat? “Dammit, maybe the 600g pack might have been a better deal than the 375g after all.” Only when the ACA workshops the problem.
In real life customers don’t care. If price is an over-riding issue for a customer he’ll buy the cheapest pack in the category anyway and move on. He has more important things to do at home, like trimming his toenails.
Single person households have been a growing demographic for many years. Why would a solo resident be interested in the 1kg family pack of shredded cheddar cheese - even when it’s on special - if most of the pack will turn into a lump of grey-green mould before she could possibly eat it? No, she’d rather buy a smaller pack, knowing she will finish the pack while it’s in good condition, with a savvy net saving of maybe $2.
People know from experience the pack size that best suits their needs.
Australian households have trended smaller because of late marriages and delayed child-rearing, smaller families, higher rates of separation and divorce and the fact women generally outlive their male partners. The bigger, “economy pack” sizes are not all they are cracked up to be, for people in such circumstances, even if they are a boon for the family of six. Shoppers know this.
At the end of the day, grocery customers can be trusted to do what’s best for them. They’ll buy on instinct or experience or just save time and grab whatever is nearest. It’s always a matter of priorities.
But there’ll always be people who know better.
