Accept Discount Codes On Cart

Dr. Discount On Cart provides a customizable Discount Code field on the Cart page, so customers can see their savings before checkout!

The coupon code field is integrated into a professional cart summary section, which also displays the subtotal, optional shipping estimate, and final estimated total. All of the labels as well as their styling are customizable using a friendly interface that does not require any coding skills. HTML is supported if you choose to use it.

Accept Discount Codes Everywhere

Our app lets you accept discount codes ANYWHERE on your site! Overlays, product pages, home page, and more. It's so easy and reliable to use.

To help with customization, we let you specify labels, messages, and styles for the standalone coupon fields separately from the settings for the cart summary.

FREE Shipping Tier Compatible

If your store offers free shipping, our app can promote it in the cart summary using an optional customizable message.

For instance, if the order subtotal is $35, and your Shopify shipping zone has a free shipping tier set up at $50, then the message could read “You are $15.00 away from FREE SHIPPING!”. When the customer reaches the $50 minimum, the message changes to “You got FREE SHIPPING!”. Both messages as well as their styling are separately customizable.

Shipping Estimation

To be able to promote a free shipping tier, shipping estimates are generated by evaluating your store’s shipping zones that have manually entered rates. If your store is only using 3rd party rates (UPS, FedEx, etc.), then our estimator and free shipping promotion tool will not be available.

Our Dr. Shipping Calculator app is a better fit when 3rd party rates are in use.

Breezy Installation

Whether you choose to use our self-installation wizard, or would like to copy/paste our single-line code snippet into your Cart page template, or you prefer to have us help you with a free professional installation, you will be up and running with Dr. Discount On Cart in no time!

Development Stores

We are developer-friendly! If you install our app on your development store, you can use the app free of charge.

We will not charge you until the store is transferred to a client. At that time you will need to re-subscribe at the regular rate.

Currency/Money Formatting

Our coupon fields and the cart summary use the currency and money format that you have already specified in your Shopify settings.


Our process ensures that coupons are applied as fast as possible, so customers don't get frustrated with long wait times (like you may have experienced with other apps).
