The big dealers mentioned above all are fine. I might add Rockymountainbullion. They may be a little slower but sometimes have good prices. Vermillion Enterprises out of Spring Hill, FL is a smaller business with good prices. (I haven't actually used them yet but they have a good reputation.) They frequently put out a video discussing premiums. APMEX is often on the higher side. Shop around, compare prices, check out the "On Sale" tab on their web sites too.
