Best buy, please help me on this! very disappointed and frustrated!!

Question

Here is my complaint:
1.I have been saving for weeks trying to buy this flat screen TV: the price has been $299.99
http://www.bestbuy.com/site/westinghouse-48-class-48-diag--led-1080p-hdtv-black/6233067.p?id=1219198...
Then finally this Tuesday I went there to buy, I checked the online price, it jumped to $329.99. I do have a mover coupon which is good for 10% off a single item. So I used, but I will have been really happy if I could have used it when the price is $299.99 instead. This mover coupon said any single item with some exclusions and I believe this Westinghouse 48" is not in the exclusion list.
After I bought Tuesday, I checked the price online today, man, it went back to $299.99. Your price mathcing policy said if the price lowered within the return period, we could get the difference back. Then I went back to the Best Buy at Fairlawn, Ohio (Montrose) location where I bought my TV. But they refuse to return the difference saying I used that coupon.
But key issue here is not using the coupon. That coupon DOES NOT SAY anything about not using on a sale item at all!!!!!
If I return the TV today and they give me back that coupon, I would have been able to buy this one again at $299.99 AND using that coupon again!  So It is very UNFAIR they are doing that.
Very disappointed and frustrated. Please help me to get this issue straightened out!! I follow all the rules, but that store clerk did not seem to understand that coupon is good for on sale items too and that TV is not on the exclusion list so they should follow the price matching promise and issue me the credit!!!!!!

It does not have Westinghouse TV mentioned in the exclusion list and I donot believe it is a UMRP product!
