How supermarket customers decide
Supermarket shoppers plan around promotions and check whether something is in stock at the branch they can reach. Chains publish a promotional leaflet as an image, which cannot be searched, cannot be linked to a product, and is out of date within the week. Online grocery is the other gap: the demand exists, the logistics are hard, and most regional chains cede it entirely to delivery platforms that then own the customer relationship.
What we build for a supermarket
First, a searchable catalogue with stock per store, since shoppers want to know it is there before travelling. Second, promotions as structured, linkable offers rather than an image, so a shopper can build a list around them. Third, online grocery with delivery slots and substitution rules, because substitutions handled badly destroy repeat orders. Fourth, loyalty tied to a phone number with personalised offers, which is the only durable advantage a chain has over a platform.
