Please leave me a PM if you would like to order. I can do deal straight away. I am running out of coupons for Antminer S1 (~40 coupons left), but I still have +100 coupons for Antminer S2 (worth together 40k USD).

I also updated first post of this thread:

Current prices:

1x Antminer S1 180 GH/s: 0.027 BTC off the BITMAIN price
1x Antminer S2 1 TH/s: 350 USD off the BITMAIN price

For example:
Today (13 May 2014) Antminer S2 on BITMAIN website costs 2424 USD. If you buying from me, you will have it for 2424-350 = 2074 USD only.
Same with Antminer S1: on BITMAIN website it's 0.476 BTC right now. If you buying from me, you will pay only 0.476 - 0.027 = 0.449 BTC.

Update:

I have some BTC in hot wallet, I can do ESCROW for your order. Please PM for more details!
