These coupons are now transferrable on Bitmains website, and I have extra coupons that I will not be able to use before they expire.
I have 29 Antminer S1 .05 BTC coupons that I will sell for .02 BTC each. These expire on 5-29.
I also have 24 $400 S2 coupons that expire between 5-23 and 5-30. I will sell the S2 coupons for .1 BTC each.
Please send payment to 15ShCe1wYrVAu9aMWK5Bv7S9i7cikY1CNm and either include your Bitmain id in the transaction or PM me with your userid and transaction number, and I will transfer the coupons as soon as I can. I spend way too much time on this forum, so it shouldn't be longer than an hour or two unless I am sleeping...
I am happy to use a reputable escrow service like OgNasty for larger transactions as long as the buyer pays the escrow fees.
If these don't sell in a day or so, I'll probably just end up giving them away, but they could come in handy for someone that wants to purchase a lot of S1s or S2s soon and doesn't have any coupons.
