Third, to attract the right customers, you should give your product a high price point: somewhere between $50 and $200. This will not only give your product a premium image; it’ll also increase your profit margins and decrease the likelihood of complaints. The logic here is that anyone who’s prepared to dish out that much money will be less likely to complain if the product doesn’t live up to expectations; they’ll have money to spare and won’t care enough about the loss to make a fuss.
