Bying and downloading scores is really sure and simple (see the message from Louise Malone on the guest book). You do not enter your cart number on our website because all the transaction is made thanks to Paypal. Paypal has been developped by eBay and most of websites are using it. With Paypal, you can either use your credit card or pay with your email address if you have created a Paypal account. The process is well describe here:
https://www.paypal.com
During the transaction process, you can check if there is a little yellow key (

in your Internet browser. The begining of the address starts with : https:// (with an "s" at the end of "http")
When the checkout is complete, an automatic email is sent to the valid address you gave to Paypal. This automatic email contains links to download your scores. With Acrobat reader you can read, print and save your scores (pdf format)
