Provides coupons or vouchers for the commerce extension. You can create coupons with money amount, percent amount, or also give an extra article for free or with a special price. You can set a minimum order amount or set a maximum coupon amount (for percent coupons). It is also possible to include or exclude categories for each coupon.
If you have a huge number of individual coupons, you can import them as csv file.
Coupons can be activated and deactivated by the TYPO3 time and usergroup functions.
The Manual ist mostly written in German at the moment which is not the best, but there are also helpful screenshots.
Another todo is the coupon statistics.
