Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureShopify's native percentage discounts have no way to set a maximum discount amount. A "20 percent off" promotion on a $2,000 item gives $400 off — even if you intended a $50 cap. DiscountLock adds a maximum dollar cap to percentage discounts. Set your percentage and cap amount, and the discount is automatically clamped at checkout. Caps can apply per item or per order.
Influencer and affiliate codes leak to coupon sites, browser extensions and group chats, and you give away the discount on sales you would have made anyway. LinkLock locks a code to its owner's link. Shoppers who come through the link get the discount automatically. Anyone typing the copied code without the link gets no discount and a clear message why.
- Set a dollar limit on any percentage discount to protect your margins.
- Choose whether the cap applies to each line item or the entire order.
- Same familiar discount settings you already know, with the cap built in.
- Lock codes from your affiliate app in one click, no switching apps
- Shoppers see why: "This code only works through the creator's link"
- Code health check: find guessable, unlimited, never-ending codes
- Links that expire on a date you choose; a new key disables old links
