I think it all depends on the manager, and employees, so we can't blame RS as a company. For one thing, for another, if people are switching parts, and replaceing the tape, the the RS employees are probably naively innocent, in thinking it was an unused product, and we really should be getting mad at the scammers.
Really though, I also would rather have a spare stock bumper than that 'wild' one. I hope I get scammed.
