About Carter


Allow customers to enter a coupon code before checkout

What can I do with this app?

The idea of the app is really simple: we insert a discount field into your cart! Customers can use the field to apply and see discounts before going to checkout.

How do I use the app?

We created a section inside the app called Premade configurations.

This section detects what themes you have installed on your store and checks into our database to see if we already have a configuration done for it.

We are trying to add as many configurations as possible, but if your theme is not already in the list, you can also manually create your own.

Using configurations

After you import your desired configurations you will see a screen similar to the one on our left. Initially, no configurations will be published.

If you are logged in as administrator on your storefront and you click on the preview button of a configuration, you will be able to test it out without anyone else being able to see it.

Once you are pleased with the results, make sure you hit the Publish button to make it available for all your visitors.

What is a configuration?

A configuration is a set of instructions that our app uses to render the discount field into the cart. It relies heavily on CSS selectors and has no design of it's own. To put it in simple terms, a configuration has 3 parts

-Theme: First step would be to choose the theme you are writing the config for. Configurations are highly dependent on the theme they were made for.

-Location: CSS selector which decides where the discount field will be inserted. This might require some basic knowledge of CSS/HTML. Using the Inspect Element on the cart location should be really helpful in finding the location selector needed.

-Extra CSS: By default, the discount field comes unstyled. The reason we chose to do this is because it's impossible to create a style that works for every theme. Using the same trick as above with Inspect Element can help find the classes your theme uses for buttons and inputs, creating a seamless integration.

Pre-built configurations

Most of the free themes from Shopify's Themes Marketplace have a pre-built integration ready. If your store has another theme, you can make the integration yourself in a few minutes, following our step-by-step instructions. Or we can do it for you for a small fee.

Supported languages

The app uses very little text, but we still translated every text string to allow merchants to chose their store language. Here are the currently supported languages:

  • English

  • French

  • Spanish

  • Portuguese

  • German

  • Italian

  • Danish

  • Hindi

  • Dutch

  • Norwegian

  • Romanian

  • Swedish

They have pre-built configurations for some themes but not mine (empire). I’m not a dev and even though it’s supposed to be easy, I asked Derek for some help and the day after I was all set!


I’ve been waiting for this for years. Every ecom platform allows coupons in cart, except Shopify. Thanks guys!
