I know I can use Discount Codes to provide a discount for a product, but is there a way (built-in or via an app) that I can prevent certain products from being purchased UNLESS the user enters a specific code?
Ideally I'd like to:
- use unique codes that I upload; and/or
- require entry of the unique code to view/access the product (or if that's not available, to require it to purchase the product)
As an example use case, giving out coupon at a trade show with a unique code they can enter to purchase a special product that isn't otherwise available on the store.
Thanks in advance.
