Bitmain just sent out these:
https://blog.bitmain.com/en/lunar-new-year-2018-coupon-giveaway/Would anyone be interested in my $100 coupon? I wont be buying any more miners, but figure someone here might want it. I am not trying to make any money on this, but to make it fun I will accept any ERC20 shitcoin in exchange (doesn't have to be $100 worth). PM me your Bitmain user ID and shitcoin of choice and I will send you the coupon and my wallet address. Thanks!
