There seems to be a recent trend on ebay for places
that collect
electronics for recycling to have someone who picks out the "old" items
for sale on ebay.
They have been cherry picking the incoming stuff for years. The big one around
here is Computer Recycling Center, next to Weird Stuff (who is in the same biz).
Most modern PC stuff they get goes to schools, they eBay the stuff they can get
money from, and put the dregs up for sale on Saturday mornings. Feeding frenzy
at 9:00 AM when they open. I wander by every once and a while to pick up cheap
PCI cards, or the odd bit of old software no one else wants.
Most of the store front junk stores around here disappeared as manufacturing left
the valley, and the bottom feeders from bankruptcies go directly to eBay now with
no retail presence.
