I saw on a Masters of the WWE Universe facebook group that someone found Wave 3 at a Wal Mart here in Canada.
not like I am going to find those in store cause I live in Newfoundland and apparently none of the Wal Marts here are carrying this line. I manged to get 3 of the 4 figures in wave 2 on walmart.ca
It's the same thing with the last few Wal Mart toy exclusives: Transformers G1 reissue Soundwave, the New retro Ghostbusters figures, next to no stores in NL carried them.
