My Wal-Mart does at least carry MOTU but they are filled with quite a few Vintage Collection Fakers and then New Eternia Thunder Punch He-Man's and Fisto's for Masterverse, and they have been there for months. Then they have a couple pegs full of Wave 1 of the 200X figures for Origins.
So, they do at least carry them, but very rarely move much or get anything new in. They did get the 200X stuff right on time when Wave 1 came out which really shocked me and sold through the first case they had. Then they got more and nothing has moved.
As far as Wal-Mart's near me, same situation just different assortment. So many Wal-Mart's near me are filled with Vintage Collection Zodac.
But again, at least they carry MOTU.
If they could just fulfill the orders from their website, so many of us would be golden.
