Talked to a manager about matching Black friday ads and he said he would match all ads except for the Early bird specials. So if Circuit city has an ad with something you want they will match. Not sure if this is policy, but I wrote down my managers name in case there is a question.

I work at BB, and it is policy to match competitors ads, unless there is limited quantity of the item....like the door busters. I dont think my BB will even be doing refunds or price matches that am. Also, if the item is not in stock at the other store, they can chose to not honor the price match....like on any day if walmart is offering a smoking deal on something and they are quickly out, best buy does not have to and will probably chose not to price match them.
