Setting up product discounts
When you discount a product for a sale, the lower price will override the product's default price. The customers will see the original price struck out, and the product image will show an On Sale label. To achieve this, follow these steps:
1. In Online store settings, go to Catalog → Products and open the product you want to edit.
2. Click Manage pricing options and add a Compare to price. The Compare to price must be higher than the main product price. Don't forget to save the changes.
Repeat the same steps for other products you want to put on sale! You can also set up bulk discounts!
