Supermarket shopping list: tick what to buy after you check live prices

A supermarket shopping list is not finished until prices are checked

If you are searching supermarket shopping list, you already know the paper habit: milk, bread, the brands you always buy. The gap is not remembering the ticks. The gap is whether those ticks still match today's prices, specials and unit prices before you walk the aisle.

We make Discount Trolley, so the bias is obvious. Free covers current prices, search, product pages, ordinary unit prices, Today's deals, community browsing and one shopping list. Premium adds live cross-store comparison, barcode and QR scanning, price history, comparative unit-price insight, Smart Swap, spending insights, seasonal context, dark theme and online-shopping links. Coverage is Woolworths, Coles, ALDI and Priceline where data is available. Chemist Warehouse is not covered. We are not affiliated with those retailers, and no app should promise the shelf always matches the screen.

Discount Trolley does not invent aisle badges that magically sort every supermarket layout, and it does not invent an offline catalogue. Live prices need a connection. The honest habit is simple: check prices while you have signal, then use the list ticks in the aisle. For a shopping list framed as an Australian app job, read shopping list app Australia that checks prices. For catalogues versus a live list, read supermarket price comparison Australia.

• A supermarket shopping list still needs a live price check.
• Free one list, Today's deals and ordinary unit prices cover the prep.
• Live prices and cross-store checks need a connection.

Build one supermarket shopping list with the brands you actually buy

Start with the brands and sizes you already buy, before you leave home or while you still have signal in the car park. On one My List screen in mid September 2026, Discount Trolley showed a $15.25 total and a $57.00 savings badge with Woolworths (1), Coles (2) and ALDI (0). The Woolworths line was a Minions Fleece Throw Rug at $6.25 marked Unavailable and Out of stock. The visible Coles line was Beach Road Naturals Paw Paw Extract at $1.00 was $10.00. That is the prep a supermarket shopping list should finish before you walk: you already know which lines landed, which store pills show counts, and which line is Unavailable.

When you get to the aisle, those ticks still tell you what to pick up. They do not replace a live price check you skipped at home. A list that remembers the trip beats a blank notes app that never saw today's prices.

• One Free list with the staples you actually buy.
• Store pills show where lines landed before you leave.
• Unavailable lines fail the trip before you waste the aisle.

Check specials and unit prices before the ticks win the week

On Today's Best Deals in mid September 2026, Discount Trolley showed two Coles lines with loud badges: Beach Road Naturals Paw Paw Extract at $1.00 was $10.00 with a 90% OFF badge, and Oral B Pro100 Cross Action Electric Toothbrush at $8.00 was $56.00 with an 86% OFF badge. Those are real specials from that screen. They are not proof Coles won your whole shop, and they are not a reason to skip unit price on the lines you actually repurchase.

Half-price badges still sell hard. Unit price decides whether the badge is cheap. On a Pantene Pro-V Smooth & Sleek Shampoo for Frizzy Hair 375mL product page, Discount Trolley showed Woolworths at $10.00 and unit price $2.67 per 100mL. That ordinary unit price is Free. Read it while you have bars, then tick the bottle size you actually want.

When you need a live store check on the same product, that is Premium live cross-store comparison. On the Oral B Pro100 product page, Discount Trolley showed Coles at $8.00 was $56.00, unit price $8.00 per ea, and Compare Stores said not available at ALDI or Priceline. Do that check with signal, then keep the tick on the list you will walk.

• Free Today's deals catch loud specials before you leave home.
• Ordinary unit prices on product pages stay Free.
• Premium Compare Stores when availability across chains is the question.

When Premium earns the upgrade on a supermarket shopping list

Keep Free for Today's deals, search, product pages, ordinary unit prices and one list. Go Premium when you want live cross-store comparison on the same product, barcode or QR scanning for supported products, price history, comparative unit-price insight, Smart Swap, spending insights, seasonal context, dark theme or online-shopping links.

Premium also removes the Free limits on lists, favourites, alerts and shared lists, and supports up to 10 saved stores. Saved stores remain capped at 10. Free limits still apply until you upgrade: up to 3 saved stores, 50 favourites, 3 price alerts and 2 shared lists you own.

None of that invents aisle badges for every store layout. Live compare, price history and Smart Swap still need a connection. The win is finishing those checks while you have signal, then walking with a supermarket shopping list you already trust.

3. Confirm on the shelf. No app should promise the screen always matches the ticket.

What Discount Trolley does (and does not) claim

Discount Trolley helps you check available grocery price information for your own supermarket shopping list. It does not guarantee savings, prove a forever cheapest chain, invent aisle badges for every layout, or ship a full offline supermarket catalogue. Live prices need a connection. The shelf can differ from the screen. Re-check in store before you buy.

We are not affiliated with Woolworths, Coles, ALDI, Priceline, Amazon or Apple. Priceline prices are the catalogue prices Priceline publishes online, and franchise shelf prices can differ.

When store totals disagree, decide with trip cost. For a watchlist habit on staples you repurchase, read how to track grocery prices. For a price-history habit when tags look theatrical, see the price gouging law grocery price check guide.

• No invented aisle badges.
• No forever cheapest crown.
• No affiliation with the supermarket chains.
