I rented this movie on mon. and I never got the coupon for it!!

I called a Target store to see if they have the DVD in stock and the guy said yes over 10, plus more at the front lanes. I asked him if they are the $10DVD’s and he said yes. So i drove far, to a few cities over, about an hour and a half after i made the call and I didn’t see any of the $10 ones. I only saw the blu ray $34.99. After talking w the guy who i spoke w on the phone, he tried telling me they have been busy and im supposed to believe they sold out in under 2 hours…I call B.S. I spoke w a manager and told her that he was looking at the wrong DVD. She honored the $34.99 3D blu-ray Dvd for $10…woohoo
