Just a quick post to let readers know that I have released version 1.1 of my Discount Coupons and Gift Vouchers contribution for RC releases of osCommerce.
This version fixes 1 bug in checkout_confirmation.php and includes a whole file that I forgot to include in the first version – checkout_process.php
