Hello @Tenealure thanks for your post. That feature is only available as a discount on the POS software for in-person sales. There is a Beta test concerning those kinds of coupons on your online website.

Depending on the results of the Beta testing, this feature could be rolled out to all Square Sellers, or get placed back into production for changes and more testing, or discontinued. If you'd like to know more about Beta testing, see this link.
