Interesting thread, Mark; particularly the number of guys who buy exclusively on-line. I suppose it shouldn't really be that much of a surprise, though, as over the past 5 years or so I've gone from a 50/50 split between on-line purchases and B&M's to about 95% on-line myself.
Come to think of it, about 5 years ago is when all of the nicer shops with worthwhile selections were closing up here in ATL, and I have to admit, sometimes I do miss the experience of walking into a place that was dedicated solely to smokers and smoking supplies. Even though it's a lot more convenient and cheaper to buy on-line, the smells and the wall-to-wall selection of pipes and accessories of a nice B&M were an enjoyable way to piss away an hour or so, especially while smoking a pipe and chatting with guys about nothing in particular.
I still stop in at JR's Outlets when I travel through NC, and I visit Lowland Pipes (Smokingpipes.com) at least once a year when I get to the Carolina coast, but I rarely purchase much outside of pipe cleaners, a new lighter, or a stray tin of tobacco every now and then. Of course, everything on the shelves or in the display cases at these places is available via their on-line stores, so I guess it's more about the experience than the potential purchase.... same reason, I suppose, that I drive through my old home town from time to time, and always take the time to cruise through the parking lot of my old high school.
