I searched for "waffle iron" and "tennis racket" and thought the results were pretty spiffy looking. But I'm a little unclear on the use case for this site. Say I want to buy a waffle iron, so I search for that term and get a list of results. How do I know which one to pick? If a) I had a hard maximum budget b) I wanted to get the absolute best product possible in this budget (rather than say best value possible subject to price within budget) c) When x < y, the best product at $x is always inferior to the best product at $y then I could just look for the price category just below my budget and pick one of the items there. But none of these assumptions are guaranteed to hold; in fact, in my experience generally all three do not.
