I buy rawhide and tanned leather from this
place online. What you see on the inventory pages is individual hides, showing size and quality of the piece. You have to check back regularly as the inventory changes regularly. I'm very impressed with the stuff I received from them so far, and plan on buying from them again.
I also pick up hides from a local place in Spokane, WA when I'm in the area since I prefer to look/touch a hide before I buy.
I've been offered freebies but frequently people do not know how to skin a critter so that the hide is usable, so most of them have not been worth my time/effort to use.
