The Hidden Cost of Driving to the Wrong Store (And How to Calculate Yours)
In 2026, Australians are paying more to go shopping than most of them realise. Here's the maths.
There's a cost to shopping that never appears on your receipt. It doesn't show up in your bank statement. It's not counted in the price comparison. But it's real, it compounds over time, and for millions of Australians, it runs to hundreds of dollars a year.
It's the cost of driving to a store, only to find the item you want is out of stock — or worse, cheaper by $40 somewhere else you could have gone instead.
What a Wrong-Store Trip Actually Costs in 2026
Let's build the true cost of an unsuccessful or inefficient store trip from the ground up.
Petrol costs: As of mid-July 2026, the national average for unleaded petrol sits at approximately 162 cents per litre, with prices under continued upward pressure as fuel excise relief phases out through August. The average Australian car travels roughly 11 litres per 100km. A 10km round trip to a store — modest by suburban Australian standards — costs approximately $1.78 in fuel at current prices.
That sounds trivial. But let's add the full picture.
Time costs: The ABS calculates Australia's median weekly earnings at $1,425 as of August 2025 — roughly $35.63 per hour for a standard 40-hour week. An unnecessary 30-minute shopping trip — driving, parking, walking through a store, discovering the item isn't in stock or isn't what you needed, and driving home — costs you approximately $17.82 in time alone, valued at your wage rate.
Add the petrol, and a single wasted 30-minute shopping trip costs roughly $19.60.
Multiply That by How Often It Actually Happens
This is where it gets uncomfortable.
Roy Morgan consumer research shows that Australians make an average of 3.2 shopping trips per week across all categories. Research from the Retail Industry Group and Shopfully suggests that approximately one in four shopping trips results in a consumer leaving without the intended purchase — either due to out-of-stock items, the product being unavailable at that location, or a price that turned out to be higher than expected once the shopper arrived.
That means the average Australian household — assuming two adults making shopping decisions — experiences approximately 1.6 "wasted" store trips per week.
At $19.60 per wasted trip, that's $31.36 per week, or $1,631 per year in combined petrol and time cost from shopping trips that didn't deliver what was needed.
Even at half that rate, the figure is over $800 annually — money and time that could often be avoided by checking, before leaving home, which stores appear to have the product and at what price.
The "I'll Just Check When I Get There" Problem
There's a specific behaviour pattern worth identifying: the shopper who decides to "pop in" to a store on the assumption that a common product will definitely be in stock, only to find it isn't.
This is not an unusual occurrence. Major Australian retailers — including Kmart, Target, Big W, JB Hi-Fi, Harvey Norman, and The Good Guys — carry vastly different stock levels at different locations. A product that's abundant at one store may be completely absent at another. Staff turnover and inventory management variability means that even calling ahead can produce an unreliable answer.
The gap between what you expect to find and what's actually on the shelf generates a friction cost that the retail industry quietly absorbs into the "cost of doing business" — while passing the actual time and petrol cost to you.
The Specific Problem of Discovery After Driving
There's a second, more frustrating cost pattern: the shopper who arrives at a store, finds the product in stock, buys it — and later discovers it was $35 cheaper at a store 2km away.
This happens constantly. Price variance between major Australian chains on identical products routinely sits at 10–20% in electronics, homewares, health products, and sporting goods. Without a fast way to check competing prices before leaving home, most shoppers simply don't know — and retailers are not incentivised to tell them.
The cost here is not time. It's money you've already spent and can't recover.
The Simple Fix
The data consistently points to the same conclusion: shopping trips that begin with a short check of stock availability and pricing at nearby stores are often more efficient — and less expensive — than trips made on assumption.
Find It is built for this kind of check. Before you get in the car:
- Search the product you're looking for
- See which local retailers appear to have it
- Compare prices across those retailers
- Check distance to each location
- Consider delivery or click and collect if that looks faster for your situation
A minute on Find It before leaving home can help you avoid the kind of wasted trip illustrated above — roughly $19.60 in that worked example. Your own petrol, wage rate, and trip length will differ. Always confirm price and stock with the retailer before you buy.
In 2026, with petrol prices rising and every hour increasingly valuable, the hidden cost of the wrong-store trip is worth calculating — and often worth avoiding.
Find It is a free shopping comparison tool covering a growing set of Australian retailers. Search products, compare prices, check local cues, and weigh fulfilment options — before you leave the house. Always confirm with the retailer.
