There is an Amagi metals thread on this site...there have been multiple reports from members who have placed orders and have never received what they paid for, or have simply requested refunds (if possible).
Its a shame really, since many of us really wanted to support any company who accepts BTC as a form of payment.
That comes as a surprise to me, I've actually ordered from them a few times with BitCoin and always got what I paid for. Not trying to advertise for them but they never did me wrong. I will however admit to trying to advertise for myself

I've still got a few 1/2 oz bars, a 2.5 gram bar, and a 1 oz bar collecting dust if anybody's interested, they're all sealed bars with assay cards and accompanying receipts & I'm fine with using escrow given that I'm not too well known around here.
