Q: can anyone tell me about this iTunes musicusa's ituncupertino, CA???

It's certainly a scam, if what you wrote is literally what is shown on your credit card statement. Contact your credit card company and report the charges as fraudulent.

Regards.

I too have just gotten my Amex bill and have twelve charges all around $9.99.  The problem is I know I should have a few charges with a couple of dollars here and there but never have I racked up ten dollars in a day.  I have looked all over the apple site to see a list of my charges but there is nothing in my account.  I hate to report it as a scam because I know I owe something but I can't find my charges on the website.

These are generally charges made from the ipad store when using your Amex. Not A scam.

I saw the same charge today. Went back into my purchase history and saw that the $100 charge was for iCloud Storage.

Anyone know how I can cancel iCloud Storage that I never use?

These are fraudulent if the name is "ITUNES MUSICUSA". 

My husband and I both have had these charges on our AMEX. 

If you look further into the detail, it will say it is out of Austin, TX with varying charge prices.

I have had the same issue with both my personal and corporate AMEX card. Just reported them to American Express as fraudulent charges.

Could this be Candy Crush?  Thats the only thing Ive ever purchased in months and I found some of these charges on my account as well.
