I once took a used airplane to my LHS to hang up for sale because I had my eye on a new kit in the shop and didn't have the cash. After telling the owner this, he traded me straight across the plane for the kit! I was happy because I had my fun with that plane and was itching to build another one. And I didn't have to wait around for someone to buy my plane then give the shop owner his cut. He was happy because I'm sure he sold that plane for more than he payed for that kit. I usually pay a little more when I buy from my LHS but I'm ok with that. I agree with your point and I have talked the owner down before but I am much happier to pay a little more than to have to wait around for Tower to send my stuff. I can drive 5 minutes, get the things I need today, right now. I think that alone is worth a couple extra bucks. Plus I'm suporting a local buissness that may not be here forever.
