Polygon and wholesale prices

Polygon is a network that is opened only to people in the jewelry
business. As David pointed out there is a consumer portion of the
network used as a way to promote retail jewelry and your local
jewelry.
I have been allowed limited access as a way for Polygon to
promote thier network and I am wondering if it is worth $495
for the first year and $95 a month there after.
Which leads to my question for anyone that can answer. In jewelry
manufactor/wholesale catalog, are the prices given (after taken
in account triple key) really wholesale? It has been my
experience that these people will negoitaite, but usaully on
quanities.Sometimes I am not buying quanities and feel like I am
paying to much. Would I be better off if I did all my buying on
Polygon? Thanks Steve D.
