Mac Rumors posted a news story that Apple has started refunding users who were charged multiple times for their Lion purchases.

Apple kept me on a very need-to-know basis all along, but once I confirmed the money was in my PayPal account, he then asked for a list of fees to review. Once he saw the fees (very minimal), he offered to pay them and give me a bit extra to pay any additional fees I incur. Other users who were double charged may see similar emails soon.
