How a neighbourhood shop competes
A neighbourhood grocery competes with chains on convenience, not price, and its entire advantage is proximity — which is worthless if people searching for a shop nearby find a chain instead. Delivery within a few streets is a genuine service that costs almost nothing to run and is almost never offered. Regular customers buy the same things weekly and are never given a reason to order rather than walk to whichever shop is closest that day.
What we build for a grocery store
First, a real local presence — address, hours, map, photos — since proximity only wins if people can find you. Second, delivery within a stated radius, which is cheap to operate and turns a passing trade into a routine. Third, pre-orders and standing weekly lists, because a customer who orders the same items should not have to think. Fourth, an assortment and price list you update yourself, plus loyalty tied to a phone number.
