coupon 300usd? lol, 3200-300= 2900USD

Antminer S2 2200usd - 400usd = 1800usd  

Antminer S2 1Th/s x 3 = 3Th/s (3000W) - 5400USD (every day will cut the price of 30-60usd) and shipp FAST 3days.

SP10 1,4Th/s x 2 = 2,8Th/s (2500W) - 5800USD  shipp 3-5days?


but 400usd so if you can offer coupn for all 600usd, is good price for all
