My local Wal-Mart had Rocky Balboa for the same price. I had a $3.00 coupon valid on select Sony DVD titles (I can't remember which DVD this coupon was packaged in) that was due to expire on March 31st. I asked the Wal-Mart cashier if I could use it for Rocky Balboa since it is a Sony DVD and she took it no problem. I also picked-up Blood Diamond at Wal-Mart for $14.87.
Went to BB for the Miami Vice Season 3&4 for $50 deal and it wouldn't take the $3 coupon for me either. The clerk tried saying I couldn't use the coupon, but I stood my ground until she finally got the manager. MGR: You can't use this coupon. ME: Why not? MGR: You can't pull a coupon off the cover and use it right now. ME: Excuse me, but the coupon says take $3 off right "now" when you buy Season 3&4 together. Please show me a dictionary that shows that now doesn't mean "at this moment". MGR: Well, you'll have to use this at some other time, you can't use it now. ME: Please explain why I would want to come back later to buy "another" copy of Miami Vice and end up with another $3 coupon I can't use?
This went on for awhile and the line was backing up behind me so he finally told the clerk to go ahead and take it off. She did and then I pulled out a $5 Rewards coupon I had and ended up getting Seasons 3&4 for $42 plus tax.
Everybody just needs to hold their ground and keep telling them the absurdity of their objection until they give up.
If a store manager tried to insult my intelligence by directly contradicting the wording on a coupon, I would make sure that the district manager found out about it when I got home.
