Posting a link to your own GB in someone else's GB thread is crass.
Please do go ahead and send hundreds of dollars to a newb with only 23 posts and no transaction history, who is suspiciously willing to donate hours of his time for free, just so strangers can get these coins at wholesale prices.
Or, for only
BTC0.32 extra, make your purchase from a forum member who has been trusted with money before, has experience sending a lot of packages out in a short period of time, and whose motivation is obviously turning a profit and not just running away with your money.
If you want to see what kind of train wreck you might be buying into with Silfax's at-cost GB, go look up Arklan's USB Block Erupter group buy. People were waiting two weeks for their products to get sent out from the organizer.
