I have two observations. One, you seldom see the "LHS vs Online store" comparison but in the Beginner forum. Not good or bad, just an observation.

Two, when I decide whether to pay a premium at the LHS, there's more than that 50% markup that goes into the decision. I have to decide, do I really want to support this guy? How far can I drive to support him? How far can I drive for that $8 savings? Will the extra few bucks really make a dent in my budget? Will I spot something else I need, while I'm there? Will friends be there loitering, waiting to talk to me? And (probably most important) Is this guy someone I really want to support, or would I drive the other direction and pay even more markup to buy from someone else?

I can think of a hobby shop I once patronized, fuel was not expensive, 20 mile drive, and I'd still do it if the guy wasn't such a jerk. The other hobby shop, I can walk there, he has the fuel (and other stuff) and I don't mind paying a premium. In fact, in January, I can buy in bulk at a big discount.

All been said before, I've made my decisions. I guess you'll make yours, based on the things that are important to you.

Best wishes,
