Where excatly in Bremen are you?
There are plenty of "real" hypermarkets in Bremen (Rolandcenter/Weserpark-the best one I think/Duckwitzstraße/Habenhausen/Vahr...). Their loyalty program is called Payback, which can also be used in a lot of other stores (DM-drugstores/Aral-petrol stations/Linda- pharmacies...- check out
www.payback.de for details. "real" has an online shop (
www.real.de) but only for nonfood-items. It is the same with Marktkauf -another hypermarket chain with 2 stores in Bremen. They only sell nonfood stuff online- www.marktkauf.de. Rewe and extra are popular smaller superstores/supermarkes you'll find in many areas of Bremen. One of the best places to do grocery shopping in Bremen is Perfetto. It belongs to Karstadt (
www.karstadt.de) a nationwide department store chain. You find the store in Karstadts basement in the city centre. Karstadt has a loyalty program called Happy Digits- also with a lot of other partners, Telekom for example. As far as I know they have a home delivery service for their Perfetto supermarket.
