The Artcontext Shop uses PayPal to handle its shopping cart. After you have added items to your shopping cart, you can check out using the "View Cart" button. If you have not already used PayPal for credit card transactions, you will be prompted for more information at this point. PayPal uses encrypted connections to insure the safety of your personal data. Over the past five years all of the transactions involving Artcontext and PayPal have been successful and without trouble. Legal issues related to privacy and credit card data are described in documents on the site. No information about you or your credit card is stored on Artcontext servers, and, in fact, PayPal does not reveal your credit card information to Artcontext. Your shipping address is, of course, necessary and shared by PayPal with its vendors.
