Testers wanted — help us prove one shop beats the lot
The BasketBadger closed test on Google Play is live now, and we need Android testers in the US and UK to run their real weekly shop through it. Google asks for at least 12 testers, each keeping the app installed for 14 days, before we can launch publicly — so every tester genuinely counts, and joining this week gets the clock started. Testing is free — no ads, no account with us, nothing to pay — and when the test ends, there's still nothing to pay. Shop your normal list, tell us what breaks and what confuses, and help prove that one shop really can beat the lot.
How joining works — in this order:
- Send us the email address on the Google account on your Android phone — the one you use for Google Play — using the email button below.
- We add you to the tester list and email you back to say you're on it.
- Then open the test link: play.google.com/apps/testing/com.rlosman.groceries — tap Become a tester, then install BasketBadger from Google Play. This link only works once your email is on the tester list. If you open it before we've added you, Google will say the app isn't available to you — that's expected, not a fault. Email us first, then use the link.
- Please keep the app installed for 14 days and run your real weekly shops through it while it's there — that's what the test needs.
Already testing? Send tester feedback — tell us what broke, what confused you, or what you would love it to do. Every note is read before the next build.
Send it from — or tell us — the email address on your Google account, the one you use for Google Play. Play closed testing only works with Google accounts; a different address can't be added.
Why a whole-basket comparison?
Every supermarket is cheapest at something. One store wins on milk, another on chicken, a third runs a meal deal that looks unbeatable — until you add the rest of the weekly shop. Comparing single items tells you almost nothing about what you'll actually pay at the till.
BasketBadger compares the thing you actually buy: the whole basket. We price every item on your list at each store we cover, run the real promotion maths (meal deals, buy-one-get-one-free, multibuys, spend thresholds, loyalty prices), count anything a store doesn't stock against it, add the delivery or collection cost, and only then crown the cheapest store. If a store is missing half your list, it doesn't get to win by looking cheap.

What BasketBadger does
The one-shop verdict
One clear answer: the cheapest single store for your whole list, with the full total — fees included — and how much you'd save against the typical alternative.
Every price explained
Tap any item to see why it costs what it costs: which deal applied, which loyalty price was used, and which store it came from. No mystery totals.
The missed-offer nudge
Sometimes adding one small item triggers a deal that makes the whole shop cheaper. When the maths genuinely works, we point it out — and show the numbers.
Your usuals, remembered exactly
The app learns the exact products you buy — brand, size, flavour — so your regular list is ready next time, and we can flag price drops on the things you actually buy.
Who is behind BasketBadger?
Build your cart your way and shop it against everyone. BasketBadger is created and operated by Roger Osman under the business name GETBARGAINBADGER. It is not a supermarket and it does not sell groceries — it compares your whole list, explains the total and lets you choose where to shop.

Our Promises, in writing
Short version: we work for the person shopping, not the stores. Nobody buys the cheapest spot — the lowest price you see earned its place by being the lowest price. We may earn a commission from a store when you shop through the app, but it never changes which store wins, and it comes out of the store's pocket, never yours.
