I will say, regarding prices, with the recent price hikes for toy lines across the board, TRU (at least our store) isn't all that out of line anymore. It used to be much worse around 5 years ago, but now I think SW figures are $7.99 at TRU, $7.49 at Target, and $7.54 or so at Wal-Mart. I think stuff like G.I. Joe and DCUC is actually the cheapest at TRU currently, at least here locally.
We've also been fortunate where the TRU employees here are always friendly and helpful, at least from our experience. Like I said, we usually just go in there to look around for the most part, and they are still more than willing to help us find anything we're looking for.
I also worry about WM becoming the "only game in town". Our local store has improved quite a bit, although I do worry about exclusives. Plus, like it was mentioned, it wouldn't be great to see them have even more "pull" with toy makers. Heck, I think they arguably have some of the best exclusives already this year for Star Wars (AT-ST, Dewback, Octuparra Droid, Evolutions, Comic Packs, etc.) compared to the others (Target/TRU). A lot more "all new" stuff, compared with mostly repaints at other retailers.
