Retailers, weekly ads and the fee stack behind the basket
The chain itself is a record worth having. Each storefront carries a name, a numeric id, a logo, a delivery window and a pickup window, distance from the delivery point, the aisle tree it publishes, and tags that describe the trade: Groceries, Wholesale, Convenience, Retail, Organic, Butcher Shop, Alcohol, EBT. Some banners sell alcohol, some run a pharmacy hub with prescription delivery, some accept EBT SNAP, and the warehouse clubs are shoppable without a club membership. Move the postcode and the roster changes completely: a San Francisco address returns Safeway, Costco, Sprouts, Rainbow Grocery and Mollie Stone's, while a Miami address returns Publix, ALDI, BJ's Wholesale Club, The Fresh Market, Milam's Markets and two liquor stores.
Weekly ads are a separate feed. Every flyer page is dated to a savings window and lists the deal mechanic per item, so a promotion calendar can be rebuilt week by week per banner. The basket total is another layer again: delivery fee by retailer, window and order size, service fee that varies by cart, a pickup fee where the chain charges one, priority and long-distance fees, a convenience fee on the fastest orders, bottle deposit and bag fees by state, plus regulatory fees in some cities. An Instacart+ membership waives delivery fees on qualifying orders but not service fees, so the same cart carries two totals depending on the account.
