About Carter ‑ Discount box in cart


Display a "Have a discount code?" link in cart, under the Checkout button

This feature allows customers to enter a discount code before checkout. Visually, it's a simple text link displayed under the checkout button in the cart page or drawer cart (ajax). Once clicked, it opens an order summary popup where customers can enter their discount code. You can either set it up automatically via a on/off button, or manually via the code snippet to insert in your cart's theme files.


Add a coupon field inside your theme's cart (page, drawer, ajax)

Single-click setup available for almost all popular themes. Custom templates available for developers, too. Configs editable; change text labels, translate words, edit CSS or JS.


Stack multiple discounts in a single coupon code

Smart deals are flexible and stacked discounts encapsulated in 1 coupon code, like: * 20% + free shipping * 10% on collection A and 20% on collection B * 15% discount up to a maximum of $X

Smart deals goes above and beyond Shopify's discounts to allow popular sales, like: * Discount that excludes some products or collections * Discount based on the email address (all emails ending with * Buy X units for a fixed price

It is a very useful and functional tool (apply discounts before checkout), highly recommend. Easy to use!

I must say i am incredibly impressed with this apps performance and in particular the swift response of Derek from customer services when my app temporarily stopped working. He got it back up and running in no time. Fantastic service

At first I was hesitant because I thought it would be hard to use and set up and far from it not only is the app easy to use but this is the best app i used until now. Awesome service, friendly staff. Exactly what I was looking for in an app like this.
