Absolutely, the price is the price and you're free to charge what you want for whatever goods or services you deliver. However, telling people (and friends) you got a "killer deal" on a bike (or anything else), then offering to sell to them for twice as much as you paid for it is shitty. Of course, some people like to fuck their friends/acquaintances over. THAT shit will come back to you, that's all I was saying.
