Thanks for the link. The last part really is the bottom line, as far as I’m concerned: has anyone ever successfully claimed against one of these guarantees? I really doubt it. And if that’s the case, what is the value of the guarantee? Especially to me, the site owner?
Actually, I think I know the answer to that last question, and it’s the same as for the site seal (which usually accompanies the “guarantee”)–it gives warm fuzzies to ignorant users/customers. They see the seal, they believe it means much more than it actually does, so they engage in transactions they never would otherwise.
