Let me ask you a question. The last time you launched your own product to sell online, or even offline, how did you come to a conclusion about what price you were going to be selling at? At a guess, I’d probably say you looked at the competition to see what they were charging.
While this is a good start, it’s far from the whole picture, and you’re fumbling in the dark if you look at competition is the only factor you’re taking into account.
