I and many of my friends and relatives have ordered from them. They are trustworthy and prompt.
Kitco.com is also a major metals dealer. I’ve never bought from them personally, but they are one of the biggest in the business, and I’ve never heard a negative thing about them.
Bullion is the preferred way to hold physical, I believe. Stick to widely-recognized 1 oz. minted coins like Krugerrands, Canadian Maple Leafs, American Eagles, Austrian Philharmonics and Australian Kangaroos. I stay away from coins minted from China and other non-Western countries. When TSHTF, you want to be able to easily barter/sell/trade with known quantities.
Same goes for silver. Although it’s so damn heavy that it’s actually worthwhile and preferable to go with 100 oz bars (if you can find them).
Whatever you do, DON’T buy stocks/ETFs or certificates. Make sure you hold the real stuff in your hands. When the hammer falls, you absolutely don’t want to be caught with paper.
And don’t forget about the ammo tip. Seriously, the stuff is going to be worth its weight in gold. A small investment in popular calibers will really pay off. I don’t care if you own a gun or not. All those guns out there and a decreasing supply of ammo…you do the math.
