They sure do. With at least a 6 minute gap between G block selling out and H block being released that was quite a critical gap for anyone trying to buy then. I think they can do this better.
Hopefully anyone still wanting to buy today will have their chance now.
That was a real screw-up.
All blocks should have been made available when sales opened up at 9am.
I got 1 in G block and 2 others in H block (thankfully because I stayed online in hope that it wasn't a sell-out).
