RE: Purchasing Etiquette?
And, from another angle...
Two stores within an easy drive from my home will match (or beat!) the mail order price. They're used to people asking, and they don't mind quoting a price.
Actually, though... I don't ask either one of them advice.... they're both hobbyists, but first they're retailers. Advice is best sought at the club level, or the manufacturer level, in many instances.
That's my opinion, anyway.
