$3,878.40 paid for a piece of MAC OS X Lion, are you serious ? Yes. John Christman, on 23rd July 2011 bought Mac OS X Lion paying $31.79 (Inc. Tax) from his PayPal account. After his installation he downloaded the beta of iTunes from his developers account and got his stuff an automatic restore which made him thinkis the actual reason to pay $3,878.40. He also says that he installed a fresh copy and

I fresh installed Lion, because the upgrade caused a lot of problems. My system needed as fresh start anyway.

I logged into our developer account and got the latest iTunes Beta, and installed it. iTunes has a cool new feature to download all your purchased apps for you.
I clicked download all.

As each download started it charged me $31.79. Some apps came fast, some took longer, but the timing was directly related to when a new app started to download.

Well reporting both to Apple and PayPal ended up at blaming each other, John Christman said

Apple Blames PayPal, PayPal blames Apple. They both are claiming to investigate, but I am stuck broke for three days now.

He is not the one with this problem, Apple Support Community is filled up with the same complaints.
Christman thinks it is related to the new iCloud feature that allows iTunes to automatically download previous purchases:

Above in the pic, it says Refunded but nothing s headed up for Christman. He said

Apple claims there was only one transaction. When I told PayPal to dispute them, they closed the cases and marked the items as refunded on the 23rd. Bear in mind all this money was taken and never returned yet.

And at last his mortgages..

My mortgage is due in 2 days, and thanks to them, I don’t have the money.
