Paypal is the credit card processor for this web site. You do not need to be a Paypal member to pay with your credit card, making Paypal no different from any other credit card processor, with one key exception - the vendor never sees your credit card information and thus the transaction is much more secure. I have personally had my credit card info exposed on the Internet three times by web sites with security issues. That can't happen here!
We take privacy seriously - we do not purchase customer lists and we do not sell customer data. There is no prompt to be added to a mailing list - our rare emails (once or twice annually) only go to customers. Removal is as easy as replying to a RARE email and removal is manually done by a Human (or Martian). Customers are automatically added to the customer mailing list unless otherwise stated in the order comments or previously removed.
