Sorry to post suck an ugly post in the Halloween event but i seem to be having an issue with the event store, it will not let my buy any of the items. Anyone know why this is?

Actually, no, I'm sorry.
Try posting you issue in the Information Desk Forum.
And more people should see it, so you'll get an answer.

Edit ::
It maybe an issue with apple/gold count.
Try getting more gold and/or apples, and see what happens.

maybe your computer is just glitching, you should try logging out and logging back in sometimes that helps and is all thats required

there's 2 methods of payment by gold or apples you have to press the coin or the buy with gold button and the other button to buy with apples hope that helps.
