You'll definitely have to use the 1-888 number. Seems that just about everything listed is MSRP. For example, the V444ES is listed for $999, but I believe Magnolia Hi-Fi's everyday price for the same model for $899 ($799 a couple of weeks ago on sale).
I once got royally burned by a B&M GoodGuys. Put a hold with down-payment on an item once, had it stamped and taken into the back room. When my mother-in-law went to pick it up the next morning, she found one of the other salespeople took the receipt off of it and sold it to someone else. They offered her the floor model with zero discount, or something slightly better for just $300 more. Service isn't a specialty of theirs...I don't even walk into their store any more.
