Sometimes I lazy to go to REWE, would you sell to me some of your unused groceries?
Nearest REWE is a bit far for walking distance, sometimes after-work I feel no energy to go to groceries... I also avoid over-buy grocery because it frequently ended up in trash.
Would people in Berlin sell some of their unused grocery (with a bit margin of course) to their neighbor?
note: also I dont have good deutsch, I am affraid to knock people door...and kinda hard to explain but I am okay to pay
