Well, I'm lucky enough to be a former Best Buy employee, so I asked one of my friends who still works there if he wouldn't mind checking in the system for me. Sure enough, 8 were found, although they were not on the shelves - he did have to go in back for it, but according to him, I was probably the only one that bought it that day.
Yes, I'm a completist, and even though I have all of them, I just wanted this as well.
Interesting problem, though: The box specifically states, "Includes all available in-game retail items from these expansion packs!"
When I typed /claim, "My account is not pending any rewards."
The ONLY logical thing that I can think of is that I am using their existing 30 days free thing, and the in game items will work once it switches over to my Credit Card again.
If that's the case, though, isn't that false advertising??
