Finally had some luck with the Returns figures. Kept an eye on the ToyShiz links; the bundle popped up first on MTS, and I didn't feel like waiting for the others, so I went ahead and snagged it. Right about the time the order went through, Max popped up on GameStop, and I snagged him and Scarecrow from yesterday. Easy peasy, in and out, as all things should be.
EDIT- looks like Max is showing up in searches on GameStop, but when you click the product page, it gives an error message. Don't know if that means he's sold out, got put up early, the site is crashing, or what, but hopefully it doesn't spell disaster for anyone who got orders through.
