"It's always more to a merchant's advantage to sell 300 units at $15.00 apiece than it is to sell 5 units at $75.00 each." That logic makes sense for items that the merchant is sure the masses will want (ie., a sexy female model), but for something more niche (like, say, an accurate detailed model of the human brain, for instance), then upping the price and banking on those who really want something like that may be a good idea. You may never sell 300 units of the product, even at $15 a pop, whereby someone who really needs such a model is willing to pay top dollar.
