Actually, I'm not sure this is true anymore either. From what I've read, both businesses have gotten a cease-and-desist on all selling of shipping labels to third parties. (Apparently, that is a no-no too, in addition to the whole snake controversy.) The whole thing is a big tangled mess though, and there may still be folks buying labels...but I wouldn't count on either of those businesses for long-term shipping solutions at this time.
