Hmm I am not sure on pricing on it as I dont use transfers anymore haha. It was a while ago when I was using them, as I now do dtg printing. I am sure someone will reply that knows more then me

Have you tried tshirtsupplies.com ? I know they carry transfer paper, but I dont know what dark paper they carry. Just from reading the threads here, it seems people have gotten a pretty good price on papers from them. I would also compare Imprintables and coastal too. Although I am not sure what dark paper they carry, again I dont buy it anymore and I am simply passing info I have read in the threads

Hope this helps some.
