TBH its a 15 minute walk to the main Lidl, or a 4 minute one the other way to the nearest corner shop down here. Cant do a full shop on foot (I could steal the trolley for a bit, LOL) but eggs is doable here.
Bicycle is a great investment. I go to my lidl by bike as much as possible and do proper shopping with single Pannier bag. It's farther than yours, but it's also easier to carry more stuff on a bike.
