I went to the one here in Northern RI. The POS system had it at $19.96 but the shelf tag said $14.96. So after a brief to-do and a walk back to the DVD section to show the clerk the shelf tag, I got the two discs for $12.80 being told that the mismark got me $3 additional off. Sweet!
I experienced the same thing at the WalMart on Round Grove Rd in Lewisville, TX. This was the only WM in my area that had it marked at $14.96. I didn't get the extra $3 off for the misprice, though.
