My check was cashed last week, so who knows what will actually wind up happening. I haven't even seen anything from wave 7 show up (and none of that "You're just not looking frequently enough" as I'm in these places every day and there aren't even remnants of the case; stuff is just not shipping to retail PERIOD), so I don't know if the wave with the actual labels/forms will even show up before the offer expires. Typical Hasbro, though, to change the requirements several times after people have placed their orders. At this point, I fully expect them to say they will only accept payment in the form of seashells and you have to send 5 hands (one from each action figure) in order to get the Fett.
On a semi-related note, I was able to order a Sideshow exclusive edition 12" Boba Fett on Friday within three minutes of logging on to Sideshow's site. No issues putting anything in my cart, no issues checking out, and no issues with late email confirmations or confusion. And especially no issues with a slow site or "underestimated demand." Not directly related to the mail-away Fett, but it bears repeating that some companies obviously know how to handle online transactions.
