I doubt many bike shops buy their parts from CRC @ retail price, mind. And for the LBS, there’s two important questions, not one:
1) What’s my profit on this sale?
2) What’s my likely future profit from a happy customer, who obviously can afford to buy a decent bike in the first place, on parts, servicing, accessories, energy gels, a replacement bike in three years time….?
oh, and another:
3) What’s my potential future profit on other customers recommended by this happy customer who come to me because they’ve heard about the great service I give?
