Thanks everyone for providing your experiences. I have made identical purchases from 4 of the most popular online stores that offer precious metals for bitcoin. There were a surprising number of unexpected things that occurred during these purchases, and I've documented everything that happened at a website I built for this purpose.
http://buygoldwithbitcoin.comIf you're thinking of buying gold with bitcoin you might first read my reviews and keep up on the latest news. And please leave some comments regarding your recent purchases!
During my first two purchases from Amagi Metals and Agora Commodities, something unexpected happened in the latter which added a ridiculous additional shipping fee when ordering in bitcoin. All these screenshots are provided. Agora has since gifted me an extra coin for the overcharge.
I hope this information is useful to the bitcoin community. I have two more reviews to publish from the first test purchase, and another four purchases should be scheduled soon. It takes a lot of time with all the screenshots. I have no idea how much interest this is drawing. If you like it, please share it forward. Happy stacking!
