Before I read about the server issues, I was about to say that I found it quite amusing that for a "Doomsday Sale" the receipt email states:

  The publisher of "PRODUCT" has been notified and is
  responsible for delivering this product. JetBrains s.r.o
  will deliver the product within 48 hours.

End of the world, if the planes fall from the sky, electricity goes out and the sun starts to burn us up slowly, I don't care if I can't use it, if they can still get me the products within 48 hours, kudos to them :D
