My local hobby shop supports me, as long as I want to buy stuff from Horizon. But heaven forbid that he'd go to the time and trouble to get a dealership with Brodak, Blackhawk, or any other CL-oriented place.
So I get my parts where it makes the most sense, which means a few bulk orders, and some shopping around, and doo-dads from the LHS if they happen to be things that one may also need on a radio control ARF.
