SmartLimit: Purchase Limits

Enforce one-per-customer and lifetime limits that persist across every order a shopper places.

Other apps check what's in this order. This one checks what a customer has ever ordered. Most purchase-limit apps only cap a single order — a shopper opens a second cart and the count resets. Resellers and giveaway abusers exploit that gap. This app enforces every limit per customer, not per order — lifetime or a rolling window you choose. It holds across every order a shopper places, including express and accelerated checkout. Refunds restore their allowance automatically.
