Your customers want to buy a voucher for you to give away? Great idea, but unfortunately this feature is not in the shop system implemented.
With the modules MailBeez Newsletter Professional, however, the purchase of a voucher can be implemented with dispatch to the customer.
The new recipe "Voucher as a product" in the MailBeez Cookbook shows with a few step how you can create a product in your shop, whose purchasing then triggers sending of a voucher .
