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
