Supermarkets
German supermarkets come in tiers, from dirt cheap to full service. Same basics, very different prices.
Netto
The cheapest of them all. You can also collect Payback points here.
Aldi / Lidl
A small step up from Netto. Solid basics and own brands at low prices.
Kaufland
A huge hypermarket where you can find almost everything.
Rewe
The best value for money overall. Wide range, good quality, fair prices.
Edeka
The priciest tier. Full service and a premium range, and you pay for it.
Cheapest to priciest
Netto < Aldi/Lidl < Kaufland < Rewe < Edeka. Best value for money: Rewe.
