Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureCAPMAX gives merchants full control by adding a discount cap and maximum discount limit to Shopify discount codes. Easily cap percentage discounts, set the maximum discount value per order, and define a discount limit per market. Protect margins, stop discount abuse, and limit promo codes by maximum discount value.
Shopify'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.
- Cap discounts by percentage so customers never exceed your defined limit.
- Create different discount caps for each Shopify market you sell in
- Works seamlessly with your Shopify store to ensure consistent
- 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.
