You’re offering something for sale. If anyone (friend, foe or indifferent) wants to make a purchase, they do so of their free will, they’re not obligated. They will decide if the product is something they want to buy at whatever price you choose to set. Ergo, set the price with due consideration to the potential customers’ perception of value and not the cost. I wonder if what this is really about though, is some concern as to what your friends will think about your pricing strategy. I’m pretty confident they’ll give it less thought than you… for the potential customers it’s just “do i want this object for £XX” rather than “who does that @edent chap think he is, charging £XX for this “. They might not be able to afford it, but that doesn’t diminish its value (there are many things I would like but can’t afford… some of them are overpriced for sure, but all of them are beyond my budget).
