Loss leaders are designed to entice you into the store where the big bad sales miscreants are lurking behind poles and shelves. Armed with sales pitches sharpened by years of practice, these characters hone in on your needs as they determine which model in the line to push. My former company had it's low-end machine designed to sell for only $99, and every add showed this in bold ink. But once a customer tinkered with it, nine times out of ten they would choose a better product. Another strategy is to have few of these loss leaders in stock in order to move customers up the line once they are all sold out by lunchtime.
Plus, I got paid a spiff ($3 to $10) for every higher-end machine I sold to my business customers. So I knew how to sell the benefits of each product, and could explain who to sell them to. It all comes down to which bells and whistles you really want.
