I have a bunch of BitMain S5 $45.00 Coupons - Valid though February 4th.
0.10 BTC (Based on current BTC price) Each. Result will save you roughly $18.00 each S5 you purchase.
To order - please PM me with how many you would like and your BitMain ID (The Coupon Transfer has to be processed on Bitmain's site).
Cheers!

Can multiple coupons be applied to the same unit?
