Black Friday in a Shopify store: a 2026 checklist

Updated: 11 November 2026

Black Friday falls on Friday 27 November 2026 and Cyber Monday on Monday 30 November. This short checklist helps you prepare your Shopify store so the offer sells and nothing breaks halfway through the sale.

1. Decide on the offer early

Pick one clear approach: a store-wide discount, a discount on selected collections, or a gift above a set order value. A simple offer a customer understands in three seconds sells better than a complicated one.

Also decide when the offer starts and ends. Some stores start on Thursday evening or run the whole week, but what matters most is that the times are clear.

2. Create the discount in Shopify

Go to Discounts in Shopify admin and create a new discount.
Choose whether customers enter a code or the discount applies automatically.
Set a start and end date so the discount only works during the sale.
Test the code in the cart before you advertise it.

3. The lowest price of the last 30 days (Omnibus)

Since 2023, every price reduction in Poland must also show the lowest price of the product in the 30 days before the reduction, next to the reduced price. This comes from the Polish act on price information, which implemented the EU Omnibus directive. The Trade Inspection and UOKiK enforce it.

In Shopify you enter the previous price in the Compare-at price field, but Shopify itself does not show the lowest price of the last 30 days. Add it to the description or with a text block next to the price, e.g. “Lowest price in the 30 days before the discount: 249 zł”. Don't raise prices just before the sale to make the discount look bigger.

4. Tell customers in advance

A countdown at the top of the page a few days before builds anticipation.
Email your list with the date and time of the offer.
Put the code where it is easy to copy, not only inside an image.

5. Stock, shipping and support

Check stock on your best sellers and make sure Shopify won't sell products that are out of stock.
Orders come in over a short time. Say clearly when an order will ship, and keep the carriers' Christmas deadlines in mind (InPost, couriers, Poczta Polska).
Have answers ready for common questions: returns, exchanges and delivery times.

6. Test everything on a phone

Most people shop on their phones. Open your store on a phone, add a product to the cart, use the code and go all the way to payment. Remove apps and huge images that slow the page down.

7. After the sale

Take down sale banners and popups as soon as the offer ends. Old offers left on the page hurt trust.
Let the discount code expire.
Look at which products sold best and use that for the Christmas season.
