My favorite B&M will set aside something that he knows that I'm interested in, or he will email me. He does the same with pipes from time to time. I'm not the only one that gets this service. He is just an awesome businessman who knows how to hold our loyalty. ...and get us to empty our wallets, ha ha.
If I had to set out on a hunt, I would start with the list of B&M's on this site, and just start the fingers to walking. If a store doesn't have what I want, ask the person on the other line for suggestions of other stores that may. If each failed lead gives you two or three other leads, pretty soon, you are doing real detective work. :wink:
