They used to always have a case with some Fudd guns in it at our local here. Come to think of it though, I think you're right - I don't recall seeing them on my most recent visits (I always go to that department to check ammo prices).
Fudd guns do not interest me, so it wasn't like I was ever going to buy a gun from them, but it is concerning that the anti's have pressured them into acquiesence now too.
The day I see the "no CCW allowed" sign posted on their front door is the day that Wally World loses my business forever.
EDIT: It might be kind of interesting for one of us to write a letter to the CEO of WALMART asking them what, exactly, their corporate position on the 2nd Amendment and all related issues is (CCW, ammo sales, gun sales), then post the reply here in the forum for everyone to see. And, I might just do that!
