You have us.
Every price cycle, every hidden pattern, every unit-price catch — we built a tool for each one.
See through price cycles
Not every "special" is a great deal. Our price history charts show weeks of real data — if a product was $4 last month and is now "on special" for $4.50, you'll see it instantly. Know the real low, buy at the right time. Every product has a chart.
Price history tracking
See how prices change over weeks and months. Regular dips = wait for the next one. Flat at the bottom = buy now. Data that turns guesswork into strategy.
Barcode scanner
Standing in Woolworths wondering if Coles is cheaper? Scan the barcode — prices at every store, plus the full price history, in under a second.
Smart Split
Build your list, hit Smart Split, and we show which items are cheapest where — "7 at Woolies, 4 at Coles, save $14." You decide if the extra stop is worth it.
Cross-store comparison
Search once, see prices at Woolworths, Coles and ALDI side by side. Sorted by unit price — cheapest first. We calculate $/100g so you don't have to.
Shared shopping lists
Build your list and share it with your household in real-time. Add items, tick them off as you shop — everyone sees updates live. Set members as editors or viewers. We'll tell you which store has the cheapest total.
The Wednesday cycle
New specials drop every Wednesday. Check "Coming This Wednesday" from Saturday for a sneak peek — plan your shop before the deals even go live.
Shop in aisle order
Toggle Aisle Sort and items rearrange to match your store layout. Walk through once, no doubling back. We have the layout of thousands of stores across Australia.
Watchlist alerts
Track products and get notified the moment they go on special. Set it and forget it — we'll tell you when to buy.
Personal inflation tracker
YOUR grocery inflation rate — not the headline CPI, but actual price changes on products you buy. Category breakdowns, top movers, trend lines in the Insights tab.
Nearby stock checker
Check if it's in stock at your local store before you drive there. See exact aisle locations too — aisle 5, right.
Community clearance reports
The best markdowns never hit the catalogue. Shoppers report in-store clearance finds near you, other locals confirm if they're still there, and you catch the yellow-sticker deals the supermarkets never advertise.
Works offline
Shopping list and recent specials cached locally. No signal in the supermarket? No problem.
Know when a deal is real
Prices go up and down in cycles. Our price history charts show weeks of real data — so you can tell a genuine special from a price that's just come back to where it was.
If a product was $4 last month and is now "on special" for $4.50 — you'll see it instantly and know to wait for a better deal.
Scan. Compare. Save.
Standing in Woolworths wondering if Coles has it cheaper? Scan the barcode. In under a second you'll see every price at every store — plus whether it's been cheaper before.
Works with every product at Coles, Woolworths and ALDI.

Frequently asked questions
Everything you need to know about Discount Trolley.
A grocery price comparison app built for Australians. We pull publicly available pricing from Woolworths, Coles, and ALDI into one place — compare prices, track price history, find genuine deals, build smarter shopping lists, scan barcodes in-store, and discover the best time to buy. Plus a whole community layer: deal voting, clearance reports, leaderboards, and points.
All pricing is sourced from publicly accessible information available online. We aggregate data from multiple sources and update it multiple times throughout the day. When shoppers spot a discrepancy, they can submit a price correction through the community features — keeping the data honest for everyone.
Woolworths, Coles, and ALDI — the three biggest grocery retailers in Australia. We're always looking to expand based on user feedback.
The core features are completely free — price comparison, price history, barcode scanning, shopping lists, search, community features, points and leaderboard. Premium unlocks extras like additional store slots, multiple lists, unlimited saved items, extended price history, and shared lists.
This can happen due to timing (price just changed), regional pricing (some stores have location-specific prices), in-store-only promotions, or clearance markdowns applied at individual stores. If you spot a difference, submit a price correction from the product page — it earns community points and helps other shoppers.
We automatically detect products where the "was" price looks suspicious — like when a price was inflated shortly before a "sale" started. If a product was $5 for months, jumped to $7, then went "on sale" at $5.50 — that gets flagged. The price history chart lets you verify it yourself.
All three chains refresh weekly specials on Wednesdays. ALDI also launches Special Buys on Saturdays. The Home tab updates with fresh specials shortly after they go live, and "Coming This Wednesday" previews next week's deals from Saturday onwards.
Smart Split takes your shopping list and checks the current price of each item at each of your selected stores, then calculates the optimal split — like "buy these 8 at Woolworths, these 5 at Coles" — with exact savings shown. You decide whether the extra stop is worth it.
Toggle Aisle Sort on your shopping list and items rearrange to match the physical layout of your selected store — Aisle 1 items first, then Aisle 2, and so on. We have aisle mapping data for thousands of Woolworths and Coles stores across Australia.
Yes! Tap the share icon to generate an invite link. Everyone syncs in real-time — add, remove, and check off items together. Set members as editors or viewers, manage roles, revoke access anytime. Both users need to be signed in with Apple.
Tap the scan icon, point at any barcode, and instantly see prices at every store plus the full price history. Standard barcodes and GS1 QR codes both work. Scanning earns community points — and scanning new products earns bonus points.
Everything you contribute earns points: scanning (5pts), voting on deals (2pts), price alerts (10pts + bonus if confirmed), corrections (10pts + 30 bonus), store notes (5pts), daily login streaks. Climb five rank tiers from Newbie to Trolley Legend. Weekly leaderboard resets give everyone a fresh shot at the top.
Community-submitted in-store markdown finds near your selected stores. Other shoppers spot clearance stickers, report them, and you see what's been found nearby. Shoppers can confirm reports ("Still there") to boost trust. These markdowns don't appear in any online system — the community is the only source.
The Insights tab builds up from items you check off your list: monthly spending summaries, category and store breakdowns, savings tracker, personal inflation rate, budget tracking, seasonal pricing intelligence, a "Could Have Saved" estimate from Smart Split, price drop feed, and personalised savings tips. The more you use the list, the smarter it gets.
Your personal grocery inflation rate — not the headline CPI, but actual price changes on products you buy. Shows category breakdowns, top price increases and drops, weekly basket comparisons, and a 6-month trend line. A reality check on whether your bill is going up because of inflation or changed habits.
No. Guest mode gives you full access to price comparison, price history, barcode scanning, a shopping list, search, and viewing community data. Sign in with Apple unlocks cloud sync, community participation, shared lists, and device-to-device restore.
Shopping lists and spending data stay on your device. Sign in with Apple uses anonymous relay email — we never see your real email. We don't sell data. We don't share shopping habits with retailers. Community contributions are anonymous. You're the customer, not the product.
Go to Profile → Danger Zone → Delete My Account. This permanently removes your account, all cloud-synced data, and local data. It cannot be undone.
