I'm sure you know this, but I'll say it anyway...
hype = sales.
Latest & greatest (?) = Sales.
System synergy (or lack their of) = sales
Money woes = sales
... also likes and dislikes, etc. all equal sales. Popularity too accounts for merch trading hands. On any given day look at the numbers of REL, Velodyne, Cardas, Shunyata, BW & Pass gear available.
Should numbers of listings indicate an item good or not so good?
I also think as there are numerous BM outlets for these same items, the volume being traded here makes a statement as well. Either BM's will adjust to the webs influence, and/or become more flexible with their cash paying customers, or they'll miss out on a share that could well have kept them going a while longer.
Around my local area, one can expect only 20% off on demos but with warranty yet no in house service. That's at just one place. The other's don't do even that. So my general area sucks for BM deals, and service. Just one has customer - people skills worth a darn too. Far as I'm concerned, and a number of others about me and here on A'gone, there's only one place to even try looking to for A&V gear sales. Consequently, the Web and phone calls to makers selling direct is truly the only way to go... but I still try to deal with the one BM worth going to here.
People in general, respond to being treated with respect. They also respond to being treated otherwise. The response merits both paths accordingly.
