Buy Gold Bars

I know a place where to buy gold bars here in our nearby area. I went to that store a few times with my hubby and my in-laws. I haven’t seen big gold bars but they do have the small ones. I told my hubby that if I have cash, I want to put it in gold bars and he thinks that it is a great idea. Since most gold bullion bars are recognized by most retirement/IRA accounts and are traded daily, I want to put my retirement fund in them.
