After the update when I was trying to get my Runelords bundle purchase to show up, I went through the new store exclamation marked tabs and the Legendary Dice Bundle was priced at $6.99! Thinking that part of the update was a new price structure, I bought it. Two days later I get my receipt from iTunes and I've been charged $39.99! I'm currently in touch with Apple to try and resolve this, but they suggested in the last e-mail that I mayneed to contact you. Currently, I can't access the Dice tab in the store, so you must be aware of an issue.

It's definitely not 6.99.  You might have been looking at something else accidentally, or it might have bugged out.

I wasn't looking at anything accidentally. It was $6.99 after the update, when I purchased it. Soon after the dice tab in the store became unresponsive. Now it's back up and listed again at $39.99. If it was a bug, that's fine, just refund my money and remove the purchase from my account.
