Thanks for the link and the website, I was checking apmex.com and found out they were selling different types of gold what is the difference between this one http://www.apmex.com/product/39598/1-oz-gold-buffalo-random-year and this one http://www.apmex.com/product/11951/1-oz-pamp-suisse-gold-bar-9999-fine-in-assay...I bought the previous one before... and how do you make payments? do you use credit card or wire? looks like using wire is cheaper but I have never used wire transfers in my life before.
