Extra orders. You pay only when they happen.

After each purchase, extra carts finds the next purchase your customers actually want — and sends exactly one fitting recommendation, an hour after they buy.

• Install in your Shopify store. Three approvals: OAuth, a spending cap, the data processing agreement — that is all the setup there is. We read products, orders, customers. We never touch checkout, payments, or your sender domain.
• Your price is derived — before anything is sent. We import your order history, compute your average order value, detect your category and derive your CPO from it: Amazon's public affiliate rate × your average order. One number, locked before the first send.
• It sells while you sleep. After every purchase, extra carts checks co-purchase patterns, consent and product similarity — and sends exactly one fitting recommendation an hour later. Conservative templates, hard frequency caps. You see results, not a flow builder.
