New stuff found recently: Spider-Woman at a grocery store I stopped at on the way to Dallas (I passed on it, stupid move in retrospect) and Mary Jane at a local Target, but they wanted $9 and I wasn't willing to pay that.
Other than that I just see the same 4 versions of Iron Man on the pegs.
I did see Galactus at TRU the other day though, which was pretty cool. Of course they upped the price along with everything else in their store but yeah.
