My BB store wasn't accepting BBBs on any of the doorbusters at least on BF. I had a $3 coupon, and I really don't shop BB that often so I threw it on the counter when my sister was paying, and the associate said he didn't think they were accepting BBB on the BF merchandise. My sister got the emachines and 2 of the 3.99 dvds, so i figured maybe it would work on the dvds, but it didn't.
They lied or were misinformed. You might want to try taking your receipt, your BBB and a copy of the BBB terms and conditions back to the store. Advise them that they improperly refused to accept your BBB on BF. Request a refund for the amount of the BBB or at least a store credit/gift card.
You can find copy of the Terms & Conditions in this thread
