Gold Buying 101

[tiw_prash]

I am new to any kind of investing and have never bought gold before.
As they suggest, i am trying to diversify my investments.

I wanted to buy about 10 ounces of gold. The market seems right to buy now.
I want to buy 24 carat variety and give minimum margins (i think Gold bar may be best). And i want to keep the gold physically.

Can anyone tell me some reliable ways on how to buy Gold and what it involves ? Does buying from some states save us sales tax etc ?
And how do you sell this gold when the time comes ?

Thanks in Advance
