There are several mints on the internet where you can buy bullion in coin or bar form. Ebay is also a good place (if you are the winning bidder). Most of the gold and silver on eBay that sells at a “Buy it now” price is over priced.
The mints on the internet usually charge $0.79 to $2.99 over the current spot price of either gold or silver. Sometmes, if you create a userid on their sites, they will also send you emails when they have something on sale.
I watch the spot prices continually and only buy when I sell a good size fall in the price, since the precious metals market can fluctuate by good sized amounts on any given day.
Hope that helps...
