You can find almost anything your heart desires in shops in Rhineland-Palatinate. You can shop at weekly markets, local shops, larger shopping centres or outlet centres.
Weekly markets are set up at designated locations, usually once or twice a week. You can find regional products there, sometimes at a slightly higher price than in the supermarkets.
Purchases at supermarkets are not bagged for you. You can purchase plastic or paper bags at the register. It can be advisable to bring a bag from home.
Another German specificity is the deposit system: A deposit is paid on nearly all beverage bottles and cans. You can return the empty containers to the supermarket to receive your deposit back.
The customary means of payment in Germany are cash, EC card or credit card. Many smaller shops only accept cash. EC cards are sometimes only accepted starting from a minimum purchase amount. Credit cards are not very common.
