If you can find the item you want at BrandsMart at Wal-Mart, take the BrandsMart ad with you and price match at Wal-Mart. Especially if you can buy it in advance, and then bring in the receipts and ad on BF and go to Customer Service for a price adjustment.
Are you planning on going to the BrandsMart at Sawgrass Mills Mall? (I grew up in Hollywood, FL so I know it well). My experience there has not been good over the years. I really recommend you try to price match the items you are interested in at another retailer. Does Best Buy or Circuit City price match? I'm up in Gainesville, FL now, and will be close to Orlando for Thanksgiving weekend visiting FIL. I'm pretty sure you'll find either of those retailers in Orlando.
