If anyone is going to try to return to store - go online and print out the "easy return receipt" since it says Blu-ray on there....should be enough ammo to get shipping refunded too.
I just got a full refund via Paypal after sending the DVD back through the mail. I sent it in last week after sending an e-mail to Walmart customer support asking if I could get one.
Yeah I just took mine back to the store last week. I think the guy wasn't paying attention and gave me tax back twice, but obviously it wasn't enough for me to even care enough to verify.
