What's the difference between coupon codes and automatic discounts?

Coupon codes require the shopper to enter a code; automatic discounts apply with no code.

How do I create a coupon code in Shopify?

Go to Discounts > Create discount, choose the type, set conditions and limits, and generate the code.

Can a coupon code stack with an automatic discount?

No — a cart can have one automatic discount OR coupon codes, not both at once.

How do I stop code-stalking?

Reserve codes for tracked campaigns and use automatic discounts for storewide sales.

Can I track which channel a coupon code came from?

Yes — unique codes per email, ad, or partner give you clean per-channel attribution.

Overview

Coupon Codes are promo codes customers enter at checkout to receive a discount — the customer-facing counterpart to automatic discounts, which apply with no code. They're created under Discounts in the Shopify admin and can be percentage, fixed amount, free shipping, or Buy X Get Y.

They're the same mechanism as discount codes — the terms are used interchangeably. Codes are limited by date, usage, customer segment, minimum spend, and product or collection, and they're ideal for tracked campaigns where you want to know which channel or partner drove the sale.

The risk with coupon codes is 'code-stalking' — shoppers hunting for codes before checkout — which is why many brands reserve codes for tracked email, affiliate, and ad campaigns and use automatic discounts for storewide sales. Unique codes per channel also give clean attribution for email marketing and PPC.

Using Coupon Codes Without Eroding Margin

1
Reserve codes for tracked campaigns
Use automatic discounts for storewide sales so shoppers aren't trained to hunt for codes.
2
Set a minimum spend
Tie codes to a cart threshold so they lift AOV, not just discount it.
3
Cap usage
Limit total and per-customer uses so a code can't run away.
4
Segment distribution
Send codes to specific segments via email rather than blasting them publicly.
5
Measure incrementality
Track revenue and margin per code to confirm it grew profit, not just revenue.
