My experience was not a bad one.
I was doing some cleaning and came across my old/broken solid gold chains from years ago which were no longer good to anyone. They would have otherwise gone into the trash, but I saw the commercial "cash for gold"...get your gold kit.
Figured I had nothing to lose if I got nothing in return in this particular case. It was two chains that could no longer be used which were twisted and broken. The kit came to me in the mail free of charge and postage paid. Within 10 days I had mailed in my gold, and rec'd a check in return for $18.00 which I have already deposited and cleared.
That was more than I would have rec'd throwing it in the waste basket and I was a happy customer.
I used the extra little bit money to put gas in my car. I hope other people can have a similar positive experience like mine.
