I don't care about emoticons, but I do care about jacking the price around and then refusing to refund the difference resulting from my BTC order being the day before the ensuing price drop.  If I accepted biting the bullet on paying the $419, then Bitmain has no business refusing to refund the difference at $369.  What good are two coupons that require another dual S5 purchase given:

1) My plans include no further S5 purchases (have four including the two just ordered).
2) I have no more BTC at this time (I'm a fixed income home miner, not a data center).
3) The coupons are only good for about half a month.

What kind of reputable business doesn't honor its own pricing?  Since when does a limited time/limited target coupon equal refund?  If the price difference were even held in account, it would be something, but these damn coupons are useless to me.  Bend over is right!
