As far as mail goes, you won’t get any snail mail from PayPal. If the gift must be shipped, the merchant who ships the gift to you may send mail to the address you provide, unless you read the checkout information carefully and are able to opt out of future communication.

PayPal can be linked to a bank account or credit card. If she does her banking online she will see the transaction in account activity on her banking website after it posts. It will not name the item, but it will list the amount, and “PAYPAL”. It will do the same on a bank account or credit card paper statement.

If you haven’t used PayPal before, you should know you have to provide financial information and have it confirmed the first time you use it. You should register quickly if you want to use PayPal and have your gift by the end of the week, especially if you are not using online banking yourself already.
