Why don't you guys just make your own...go on one of those DIY punk forums or something. They show you step by step how to make screen patches...then make some Dismember, Entombed, Grave...ones while you're at it. Look you're a pure death mettaler now...no one will fuck wit ya!
I also thought about that, but it would cost over 70, because all companies I found have a minimum order of 100 patches.
Do you have a link of the company?
