Supermarkets in Poland: Biedronka, Lidl and Żabka explained
The essentials: Compare the prices of your own basket, check promotion conditions and confirm your chosen shop's opening hours. Most Sundays are non-trading; the Labour Inspectorate lists eight general trading Sundays in 2026. Deposit-marked drinks packaging can be returned at collection points without a receipt.
Correction, 30 October 2026: We corrected the shopping-Sunday frequency and removed unsupported corporate, cheapest-chain, universal-payment and branch-opening claims. This is not an independent price test.
Grocery shopping is easier when you know how to compare offers, check Sunday hours and return deposit-marked packaging. This is a practical orientation, not a tested ranking of the cheapest chains.
Compare the shops you can actually use
Biedronka and Lidl are discount-chain options; Dino, Kaufland, Auchan, Intermarché, Netto and Carrefour are other names you may encounter. Żabka is a convenience-store option. Check the individual branch, opening hours and range rather than treating the brand as a guarantee.
We have not carried out an independent basket-price or app test. Compare the unit price and your total basket. Promotional prices may depend on a loyalty account, activated offer, minimum spend or quantity limit. Read the terms rather than assuming every app offer saves money.
Beyond the chains: markets and corner shops
Supermarkets are only half of Polish food life. Most towns still have a targowisko - an open-air or covered market where farmers sell eggs, seasonal fruit, honey and oscypek-adjacent cheeses - and neighborhood piekarnie (bakeries) and mięsne (butchers) do steady trade against the chains. In big cities, restored market halls such as Hala Koszyki or Hala Gwardii in Warsaw turn the same idea into a food-hall evening out. Prices at the chains are hard to beat, but for bread, seasonal produce and anything you want to ask a human about, the small players are where Poles themselves still go.
Sundays: check the calendar and the branch
The Labour Inspectorate lists eight general trading Sundays in 2026: 25 January, 29 March, 26 April, 28 June, 30 August, 6 December, 13 December and 20 December. This is not one or two shopping Sundays every month.
Exceptions include petrol stations, pharmacies and qualifying owner-operated shops. A brand name alone does not establish that a shop is exempt or open. In particular, do not assume every Żabka opens every Sunday or that every branch is personally staffed by its owner. Confirm the branch hours before travelling.
The bottle deposit that appeared in 2025
Since 1 October 2025, Poland runs a deposit-return system, the biggest change to grocery logistics in years. Plastic bottles up to 3 litres and cans up to 1 litre carry a 0.50 zł deposit; reusable glass bottles up to 1.5 litres carry 1 zł. You pay it at the till and get it back - in cash, no receipt needed, at any collection point, not just the shop where you bought the drink. Shops over 200 m² must accept returns, manually or through machines. Two rules matter: the packaging must carry the deposit symbol on the label, and it must be intact - do not crush your cans. If you don't return them, you are simply tipping the system fifty groszy per bottle. It fits into Poland's broader five-bin recycling system.
At the checkout
Bring a bag and check whether produce needs weighing before the checkout. Confirm accepted payment methods if you rely on a particular card, phone wallet or BLIK; we cannot guarantee universal acceptance, especially at market stalls. Check delivery availability and timing for your address rather than assuming an under-one-hour service.

Frequently asked questions
Which supermarket is cheapest?
We have not run a current independent basket comparison. Compare unit prices, your actual basket and offer conditions; no chain is guaranteed cheapest for every shop.
Is every Zabka open on Sundays?
No brand-wide opening guarantee is made here. Exceptions to the trading ban and individual branch hours matter. Check the branch before travelling.
How does the bottle deposit work?
The Ministry lists 0.50 zł for marked plastic bottles up to 3 litres and cans up to 1 litre, and 1 zł for marked reusable glass bottles up to 1.5 litres. Return intact, labelled packaging to a collection point without a receipt.
Can I pay by card or phone everywhere?
Do not assume universal acceptance. Confirm the payment methods at the particular shop or stall.
