This is most likely a spam message and not from apple at all. I believe you are in the United States so you would not be using the Euro as currency.
If you do have a credit card connected to your apple account then just to be on the safe side check with your credit card company and make sure there are no charges you do not recognize.
If you do not have a credit card tied to your apple account then just delete the message, as I said it is most likely spam to to be sure you will want to check with your bank or credit card company to make sure there are no charges.
If you do have an apple account that you use for itunes purchases you may also want to change the password ***** to be on the safe side, if you need instructions on changing the password ***** me know.
