200USD discount coupon for S4 at Bitmain - asking 50USD

[RedZeppelin]

I got a few S4 discount cuopons added by bitmain for my old S2 orders.
These coupon give 200USD or roughly 0.5BTC dissount on S4 orders.
Willing to sell these for 50USD/each, you need to be registered at Bitmain
so i can transfer the coupon to your Bitmain account.

Escrow possible but if you got enough good forum trust i transfer the coupon first.
