Been looking through the forum and addons for discount options without luck.

I want to be able to offer something like buy x in the store or from a category and get 10% off total etc.

I found what discounting module in the addins but that's no good to me because you have to code the discount rather than via admin pages.

The author states it's easy to do, but no good to be because the discount needs to be easily turned on/off and changed by the client so the coding route is not an option.

Is there a discount module that works via the admin that could suit?
