That's when mine was despatched (well, the day after, 5th May). It took about a week to arrive from China though. Pretty sure it was Batch #1 ... Ordered it on 25/04/18.
Yeah, but what did you pay?
Looks like I was mistaken. I was looking at the despatch email which stated I paid the equivalent of 1875 USD. The order confirmation email states that I paid the equivalent of 2453 USD (before discounts). With discounts, 1 PSU and shipping, I paid about 1.83 BCH (now about 1.2 BCH following the partial refund).
