Automatic Coupon Generator for Joomshopping!

Automatic Coupon Generator for Joomshopping!

Hello There!
I would love to have an Automatic Coupon Generator as the one advertised over here:

http://nevigen.com/en/shop/marketing/generator-kuponov-joomshopping.html#description

Nevertheless, this one is only for Joomla 2.5 and I have no idea about the company which is selling it.
Does somebody know about such a Coupon Generator for Joomshopping on Joomla 3.0?
I would appreciate very much your help.
Regards,
Albert
