Thanks Lat9 for this excellent plugin!! It will save us lots of admin time in creating customers coupons to reimburse them for duplicate purchases of our downloadable products!!

I have one question to see if you would know how I could modify it a bit. I have customers who purchase gift certificates regularly, and with this module turned on, it won't allow them to purchase it again now. Is there a way to eliminate a category id from the runnings of this program so that, in essence, the program will skip checking this certain category and allow people to repurchase???

Thanks for any help you can offer, and again, a great module!!

Jeff
