The only that I have found that still uses paypal are Eastmall and Totally Wicked. I like using my paypal account because you don't have to enter your credit card numbers. When I order something I have to get my credit card out of my purse, use it and then put it back. It is so much easier and safer to use paypal.
I rarely go out shopping and do almost all of my shopping online. I will purchase from the companies that uses paypal over those that do not.
