Shopify Discount Codes: A Complete Guide

Shopify supports several discount types: percentage off, fixed amount, free shipping, and buy-X-get-Y. You can limit codes by usage, customer, minimum spend, or date, and combine some discounts depending on your settings. Used well, discounts drive urgency and reward loyal customers; used carelessly, they erode margin.

A real project we learned from

A while back, a client came to us for a $700 store build. The work went smoothly over two weeks and they were genuinely happy — until the final request: apply two separate discounts to the same product at the same time. Out of the box, Shopify does not stack two discounts on a single item, and doing it cleanly needs a Shopify Function (or an app). The client did not want an app, and despite our explanations, they cancelled the project.

The lesson? Discount rules that sound simple — "just add two discounts" — often are not straightforward on Shopify. Setting that expectation early saves everyone time and money. The good news: with Shopify Functions, custom stacking and combined discounts are absolutely possible today. If you have unusual discount logic in mind, tell your developer up front so it can be scoped and built from day one.

For advanced logic — tiered or automatic discounts — you may need Shopify Functions. Experts Cabin builds custom discount logic that fits your promotions and protects your margins.
