I go down every isle because there's usually something hard to find stashed.
I saw Titaniums Virago and Twilight stashed behind some boxes yesterday at Walmart.
I have them so I left them.

Found a Walmart Ex. Gunship stashed a week or so ago. It was on clearance for $30.

There's sometimes weird places for endcaps and small racks with figures and Titaniums.

Sometimes I go down the Barbie isle just to see whats up (I used to buy them for my X)
I saw "The Birds" Barbie not too long ago. Now that's kindof a creepy themed toy.
"Mommy can I have that Barbie with the birds trying to peck her eyes out?"
