For a Black Friday code that gives a percentage off and free shipping, and starts and stops on schedule, use OneCode: Stackable Discounts. One code, such as BFCM20, can take 20% off everything and make shipping free on orders of $50 or more. You set an end date, and the code stops working at that time without you touching it. An $80 cart saves $16 and ships free. A $40 cart saves $8 and pays for shipping.
Shopify’s own discount codes each hold one kind of discount. Without an app, the same offer is a percentage code plus a separate shipping code, and your ads and emails have to promote both.
Which tool for which Black Friday job
| What you need | What to use |
|---|---|
| One advertised code with a percentage off and free shipping over a minimum spend | OneCode. Setup |
| Creator codes that still give something extra during a sitewide sale | OneCode, with each creator code set up as an order discount. Why |
| Checkout upsells alongside the sale | Stackable: from $19.99 a month on its listing, checked November 2026, or $99.99 a month for its unlimited upsell plan |
Set up creator codes before the sale starts
Each item in the cart gets only one product discount, whichever saves the most. That means a creator’s 10% product code adds nothing during a 20% product sale, because the sale already saves more on every item.
Make each creator code an order discount instead, and allow the sale and the creator code to combine. Order discounts come off after product discounts, so a $100 cart drops to $80 with the sale and then to $72 with the creator’s 10%.
The full weekend plan, including the end date and creator codes, is in Black Friday on one Shopify code.
OneCode costs $9.90 USD every 30 days after a 7-day free trial, billed by Shopify. You can install it from the Shopify App Store.
