Amagi Metals has gone AWOL so I would definitely not recommend them. They aren't accepting bitcoins for payment anyway and haven't for months. Their presence has been absent from the bitcointalk community for months as well.
I agree with this statement on Amagi... I have used them for nearly 5 years and have just recently stopped. Communications with their employees have shown that even they are distancing themselves from Amagi. There is no crypto accepting precious metals dealer I would recommend at the moment.
I would advise you to use gyft.com to get an eBay gift card and then purchase your gold on eBay. That is the only method I would trust currently.
have you used provident metals?
They are a large and highly reputable online (but based in the us) pm dealer. I have used them before, just havent paid with btc yet. They give a 3% discount off the "list price" when paying with btc, but a 4% when paying with cash/check.
I have used Provident Metals twice to buy silver with bitcoins (bitcoin faucet earnings) and it has been a smooth transaction for me.
