They raised the base prices half a year ago due to the exchange rate development of the past year(s), it's not just the EIDs but all sizes. *sigh* Also the EID bodies have been re-done so they're a bit (though nowhere near as much as I feared) more expensive than they were.
I seem to have missed the event completely. They're relaunching on April 1st with what they have left, we'll see how that goes ... honestly, they should just do an "event month" with only heads and bodies sold separately, stopping full doll sales for the event period, with enough notice beforehand so people can get their money together (or for those with enough funds, buy any dolls they don't want to get caught in the backlog), and they'll make a freakin' fortune.
