I was PM'd asking how all this happened. Here's a recap:
I ordered an S1 on April 30, 2014.
Bitmain shipped it via UPS on May 2, 2014
UPS updated on the web that it was to be delivered on May 6, 2014
For the following 10 days, UPS kept updating on the web that it was to be delivered the next day.
On May 15th/16th, 2014, UPS issed a loss claim.
I emailed Bitmain about getting a refund on May 17, 2014.
Bitmain responded by offering me a replacement S1 and 3 x 0.05 coupons on May 17th/18th, 2014.
I will update this post with more info in the coming days.
