Woo Custom Taxonomies Coupons

Thanks @romchyk16 for this plugin. Like @abisewski I was unable to get this to work and have spent a couple of hours debugging it. Despite an invalid coupon being present for my custom taxonomy, it was still being applied. Why was this?

Well, the plugin runs on the woocommerce_coupon_is_valid_for_product filter. This was not being run because the coupon was set for a percentage or fixed cart discount. The filter that this plugin runs on only applies to a Fixed Product Discount.

So, please update the plugin with an instruction that the coupon 
Discount type needs to be Fixed Product Discount.

Thanks, all working now :)

Excellent plugin, needs more instructions

CMS Press opens up the ability to create and manage custom content types and taxonomies for your WordPress site. 
It adds the flexibility to have more than just posts and pages for content by allowing the user to register their 
own post_types that can use their separate theming from the post and page template along with its own permalink structure.
Along with custom post_types, CMS Press gives users the ability to register their own taxonomies. With the addition of 
custom taxonomies, a user can tag or categorize content separate from the default tags and categories.
