With coupons, customers can purchase a gift certifi cate which entitles them to
money off a future purchase.
To use the feature, we of course have to install the module; it is already built
into the e-Commerce module, so we just need to check the box to enable it in
the Modules page.
Once it is installed we have a new product type, which is Gift Certifi cate.
Let's create one and see how it works.
The options available are the same as with the other products; we can enter a
name, a description, a price, as well as other options relating to the other
modules we have installed such as the Role assignments or the User account
provision. The difference with how this module works is that if we set the
price to $0.00, then the customer can choose the amount for the voucher.
