If you are simply exchanging a $50 red Farberware model ABC for a $50 stainless steel Farberware model ABC, you should have no trouble with the exchange, @my4mainecoons.
Exchanges tend to go awry when one attempts to swap a model ABC for a model XYZ, or Farberware for KitchenAid, or a $50 model for a $60 model, etc., or when one does not have a receipt and one of the items in the exchange has gone on clearance.
