WM isn't shipping anything back here... Not that I'm aware of anyway. Matter of fact they just put out more Deleted Scene figures, actually. Picked up an extra (Mc)Cracken this weekend, but wasn't much else I wanted from the wave left.
I'm with Nick, I honestly don't believe that... Shipping back is a MAJOR step for a retailer, and costs $, so I wouldn't believe that till I saw it happen en masse around the country.
I too have seen and personally heard WM (and Target, and TRU) employees spout anything they can to A) quiet you, and B) get you out of their hair.
Sucks, but I'm not the only one to experience that at, well, just about every retailer I've ever dealt with... It's a big reason I avoid customer service if I am able. They rarely do what their job title implies. The military has a fun saying of, "that's above your paygrade", and I think that's applicable.
But if figures were being sent back, repriced, and shipped out again for less money, I'd be totally in favor of that, haha.
