Price difference! WOW!
I'm lucky enough to have several good LHS's in Portland OR. They all seem to compete with each other for price, selection, and service. I really have little to no incentive for shopping on-line. I get to within 10% of the best prices going and I can actually inspect the merchandise before I take it home. That's very important to me. I also like the fact that they're there for me when I need a jug of fuel or some spare hardware. And, I enjoy going to the hobby shop.
