Accept Discount Codes on Cart, Stack Discounts, Multiple Automatic Discounts + Coupon Code Promotion
Let customers apply and combine discount codes directly in the cart, so they can see their savings before checkout. Showing discounts earlier in the buying process helps reduce friction and keeps customers moving through checkout. Multiple discount codes can be used together and combined with automatic discounts in a single step. A built-in cart progress bar helps promote free shipping and highlights savings in real time. Setup is simple and does not require coding.

Dr Stacked Discounts on Cart offers a free plan exclusively for development/trial stores — any free Shopify store can use all app features at no cost. Once a store is on a paid Shopify plan, a paid subscription is required, starting at $4.99/month (Essentials). All paid plans include a 14-day free trial, and annual billing saves 10%.
Yes, stacking is a core feature — customers can enter multiple coupon codes in the cart and combine them with automatic or volume discounts in a single step, all without typing more than once. This directly overcomes Shopify's native one-discount-per-order limitation. Stacked automatic discounts and fully customizable stacking rules are available on the Pro plan ($9.99/month) and above.
The app is explicitly designed for no-code, self-installation. It offers a self-installation wizard, a single-line code snippet option, or a free professional installation from the support team. Most merchants report being up and running quickly, and the app listing confirms it requires no coding skills.
Merchants consistently praise the app for fitting seamlessly with their store themes, and the support team is noted for quickly resolving any theme conflicts. The app also integrates with a wide range of third-party apps including PickyStory Bundles, Selleasy, Variant Option Product Options, Navidium Shipping Protection, Klarna, Affirm, BuzzSubs, and the developer's own Dr Free Gift and Dr Cart Shipping Rates apps.
The app holds a 4.8-star rating from 169 reviews, with 98% being 5 stars. Merchants consistently highlight the support team (especially an agent named Jade) as responsive, proactive, and willing to implement custom feature requests quickly. The Shopify Magic summary notes the team is "highly praised for their quick and effective assistance."
The app calculates shipping estimates based on the discounted price, not the pre-discount subtotal — a specific pain point with Shopify's native behavior that multiple merchant reviews call out as a key reason they chose this app. Note that the shipping estimator works with manually entered Shopify shipping zone rates; stores using only third-party carrier rates (UPS, FedEx, etc.) would need the companion Dr Cart Shipping Rates & Rules app instead.
Most features — including stacked discounts, volume discounts, promotional popups, and the floating discount icon — are available on the Pro plan at $9.99/month. However, merchants on the Shopify Plus plan are required to subscribe to the $19.99/month tier, which adds a load-balanced multi-server architecture and highest-priority support. This is a mandatory upgrade for Plus stores, not optional.
