Promotions
Sell your product with a discount or promotions. You can create promotions to give customers order discounts, shipping discounts, Buy-one-get-ones, and more. Each promotion can include codes and limits to how many times they can be used. Promotions will appear in the storefront if there isn't a code or can be unlocked at checkout when the customer enters a code.
Create promotional codes with a maximum number of uses.
Add promotions based on other product purchases.
Display promotions in the storefront to incentivize additional product purchases.
