I have sold to PW beck before, they sent me an airbag to post my gold to them,fully insured called me with that days gold price on receiving it to see if I wanted to lock in the god price or you can wait till it is refined and take that price, it could go up or down in those few days so it is a little gamble, I worked on a 10% overall loss on the total package 30grams of 300grams that would cover all costs postage and refining and the copper and silver impurities, it came out just about spot on and they deposit the cash straight into your account
