gw, i'm not advocating anything here but keep in mind...
if you go to the local gold/coin dealer (or many of them) and buy ingots/coins in the US, you only pay the local sales tax...fleamarkets can be a fun place to buy, if you know who you're dealing with...
depending on when/where you sell the gold there may be little/no paper work when you sell.....it's up to you to claim the capital gain...
i'm sure there is a limit to how much you can buy/sell..
the problem recently is that it does'nt work the way it used to...you used to be able to buy gold at 5% over spot and sell at 5% under....recently, these "we buy gold yayhoo's" are buying at anywhere from 20-30% below and selling at 10-20% above...be careful...it's kinda like buying/selling in venezuela from the illegals...try to be the guy in the helicopter, not the guy in the spongebob shirt...
