If I say a price is firm when I sell anything, that's my best price and what I expect to get for it, meaning I will sell for nothing less. I hate negotiating. I'm plain just not good at it. When I go to buy a good or service I pay the tag or advertised price (same as a firm price). The firm price may or not be what the "market" price is and may or may not be overpriced. To say that you won't deal with someone because they indicated the price to be firm is just ridiculous. You don't move on because the price is firm, you move on if you don't like the price. Do you argue with the clerk at the gas station about the "FIRM" price advertised on the sign out front? No, if you don't like the price you just plain go buy your gas somewhere where the price is more to your liking. Bitching about the price being immovable is a joke.

Exactly, you can't rely on those words in an ad any more than you can the words "in great shape". When I see a bunch of wear around the inserts, the seller's definition of "great shape" and mine differ greatly.
