Sounds like a move of desperation, "smoke and mirrors". In the past i have brought them proof that Best Buy was cheaper and they refused to match the price. No way they can match the retailers that they have listed and still be profitable. Also if this has always been the policy then the store management has not been informed. They also do not mention anything about matching free or discounted delivery, they have refused to do that in the past.
Until you finish your message ( You started with letter "S" at Sounds like.. and ended at "S" at Strong Sell ), they sold 100 dishwashers only in Tampa here. No kidding. I don't talk smoke and mirrors.
