Can you buy another one and return the one with the missing part with that box?
No. I don't have the extra cash to do that right now, plus that would be a crappy thing to do to someone else's kids. Frankly my son is never going to get the figures to sit on the speeder bike properly anyway, so the bike will probably stay in the back of the AT-AT for the most part (I've bought a couple of those Maestos motorcycles from Walmart and I've probably helped him put the same Scout back on the motorcylce about 100 times in the last month) . I was just hoping that Hasbro would be more like LEGO (the one time I bought a set that was missing a piece, I submitted the request and the part was on my doorstep like a week later). I get that its completely different in that LEGO actually sells their toys in parts intentionally, but still, it was worth a shot.
