Last week I noticed that Wal-Mart had the large gray (48X48 stud) baseplates in the LEGO aisle. I've never seen these at Wal-Mart before.

I imagine that they're just going to stock these during the Christmas season. Still, it's nice to know that if you really needed one, you could just go to the store and pick one up at regular price, instead of ordering one from S@H and waiting or getting one for $3 extra at TRU.
