If you still have your $250 coupon from bitmain and don't have plans to use it, please shoot me an offer as i'm looking for some. If you have a bigger amount coupon, i'll only consider those if i can use it so i will make you test it out before i take it (meaning you can attempt to buy a Z9 all the way to the point of applying the coupon and confirming that it will take the coupon). I know that the $450 coupon will not work against the Z9. Let me know! I believe they expire on July 15th if you're holding any.
