Both national and international shipping are free. Sorry to say but the reserve is 12,500 SBC, which is the minimum bid that I will trade the ingot for. I have already reduced the reserve from 17,500 SBC to 12,500 SBC. I had considered 1 gram ingots but they are too small. The postage would be 20 to 30 times the value of the 1 gram ingot in USD. I will be doing auctions for the 1 ounce ingots for 5 or 6 months. Each auction last two weeks, depends on how long my inventory lasts. After that, not sure, still planning. Maybe a web store or something.
If you know any forums or media sources, get the word out. It will help in increasing trade activity on the exchange.
