They were shipped at the same time which is why it's strange Tron is taking so long. I got Tangled and Wreck-It Ralph at the same time, in the same box, and they were shipped at the same time, so I expected the same for Beauty and the Beast and Tron: Legacy. BUT Castle In the Sky and Spirited Away were shipped at the same time and came separately. Zavvi's really got some inconsistent shipping going on...
I'd expect my steels to take longer to get to me since I'm West Coast USA and you're in Indiana. I don't know. I'm sure it'll be here by the end of the week, it's just never taken this long for something from Zavvi to get to me.
