Looks like I am late to the Party...
When online I buy from Provident, and JMbullion, SDBullion most frequesntly, and rarely from APMEX. I will buy on Ebay, but only from the big vendors like APMEX.

I like to buy locally, but in smaller qty because the pricing isnt there on generics. I have bought a TON from 2-3 wholesalers on Facebook.
