A guildie just purchased some diamonds and used Paypal. The problem is that he doesn't have enough to cover the purchase in his Paypal balance, so Paypal wants to transfer the money from his secondary payments. And that can take several days, by which the diamond sale will be over (as well as weekend sale).
Soooooo... the question is - will he get diamonds according to when he purchased them, which is today at double dias rate? Or will he get them as soon as transaction completes, which will be likely past the double dia promo.
I figure other people run into this situation, but with borked forum search, no way to find out.
