My units technically shipped "on time", however if they are under hashing I will not consider them "on time",  I will only consider 4.86 units to be "on time",  if the units  hash at full speed, then I will have little recourse for having been an early adopter and already out $1000 based on sale price not to mention the missed weeks of mining.  Caveat emptor.

However if they do not  hash at full speed then I will not have received the merchandise which I ordered and paid for and I will want to return them for a full refund,  or at the very least have the price difference refunded in BTC, PLUS coupons...   Coupons alone are not a compensation when in order to receive the value one has to spend even more money with the company.

I would also wager that they printed hundreds or thousands of shipping labels yesterday, which will be labeled the "10th",  and they will claim shipped on time even though they won't be picked up until Monday the 12th... :/
