This question comes up in other areas, not just archery. The local boutique store has to offer more personalized service to compete against the cheaper giant distributers, otherwise they will fail.
I have friends that are car dealers and run computer businesses, but I usually buy my goods elsewhere, for one reason or another. If they take offense they do it silently. Friendship goes two ways - I might be willing to give a friend the benefit of the doubt, but I don't want to be taken advantage of by a friend either.
I can say that in businesses that I own the most successful salespeople are the ones who establish relationships with customers, deliver service in such a way that price is a secondary issue. These same salespeople are less effective with buyers who have to stick to a strict budget, but even in such a situation they will ask a customer how much they are willing to spend, and then try to find a solution that meets the budget. The best salesperson I know can walk into a situation and be told that he has lost a deal. Instead of just slinking away depressed, he will immediately volunteer that the customer must need some of this other stuff. The customer, already feeling guilty about not giving the salesperson the original business, buys the other stuff related to the purchase. Sometimes the accessories total more than the original purchase and they can be much more profitable.

So what I am saying here is that it is the business of salespeople to establish relationships and to use them to further sales. It is in the self interest of customers to discipline their purchases so they know how much they want to spend and what they want to accomplish. Don't let "guilt" come into it unless you want to or can afford it.
