Goldmine has been around for a bunch of years.  I've bought lots of stuff 
from them. Most of the time, their prices are significantly below MSRP. They 
sell first class stuff, usually discontinued items and retailers' clearance 
items.

Great folks to buy from.  My only heartburn with them is their shipping 
charges.  They don't seem to have any cut-rate deals with any of the major 
shippers, but it's not like a bunch of Ebay sellers, that make their money 
with exhorbitant shipping charges. $50 to ship a 1/2 lb. item to the next 
state is a bit rediculous.

Overall, a good source of good stuff at good prices.

Cheers,
Dave M
