I'm just going by the Master Collector rag I just received yesterday.
It has pictures of all of the Wal-Mart exclusives, said it had a suggested retail price of $10, would be available in August for a limited time only.
That's really all I know other than the figure assortment which I already posted.
I should add that these are 12 inch figures. Hot Topic and Urban Outfitters had some last year and they were only $14.99.
With WalMart's purchasing power, I'm sure they can sell them for $10 and still make a profit.
