I've bought Physical from several of these well known places. Kitco, Apmex etc.. are all legit, but you have to consider their prices, shipping costs etc.. I personally buy mostly from libertycpm.com as they are close to me and I can go to their store in person and not worry about shipping. Keep in mind to buy more than $1500 to avoid paying tax and Less than 10k to avoid notifying uncle sam. Finally Ive found these two sites to be very helpful.
