Couriers refuse PO boxes, and in Canada most also refuse rural routes, general delivery and postal outlets. Shoppers type them anyway, in every spelling. Bob checks every address field for these forms in English and French, plus US military mail, and can require a street number. Then the quiet list: block an address, name, email, phone or customer, and they see only a plain "unable to accept this order". Areas and minimum orders by region too. Runs inside Shopify checkout, express checkouts incl

Shoppers save pieces with one tap, and signed-in customers see their list on any device. When something sells out, they join the line and whoever asked first hears first when it returns. Price-drop, almost-gone and reminder emails go out in your store's name with your logo, colours and wording, and replies come to you. Shoppers can share a private list, and family can mark the gifts they're buying. See your most wished pieces and which emails led to orders. No app branding on your store, ever.
