Unfortunately, you can't delete a purchased item from your order history. I checked their website and they say this: "It's not currently possible to delete items you have purchased on Amazon.com. However, you can prevent these items from affecting your recommendations--just uncheck the box next to "Use to make recommendations." On the credit card bill, it will show up as Amazon (or one of their associates if you ordered through them). The item purchased won't appear on the bill.
