Dealstub ‑ Voucher Redemption

Dealstub is built for merchants who sell through deal platforms like Groupon. Instead of manually checking voucher codes and creating discounts, you import or generate codes per campaign and the app creates a matching Shopify discount for each one, sized to the product's price. Customers redeem on your storefront: the app validates the code, blocks duplicates, adds the product to the cart, and applies the discount at checkout. Each redemption is logged with customer info.
