I second using APMEX and JM Bullion. Great places to buy.
What do you think of https://www.goldmoney.com? I have never bought but thought it was interesting since you can have it physically stored elsewhere and get a "credit card" to use like any other card. Seems like a good place to store your wealth if you think the dollar is in trouble.
they are really good, I been buying from them for years and you can get free shipping if your in the states and canada/mexico. The information you get from the site will help you learn the differences of money and currency. Mike maloney has a really good youtube page and he show some of his products there. they do store which i have some in storage.
