We exclusively use PayPal for all online payments.
PayPal is one of the largest online payment processors in the world. After rising to prominence through its partnership with Ebay, online merchants all across the Internet accept PayPal as one of their accepted methods of payments.
When you sign up for a PayPal account, you type in the credit cards and bank accounts you wish to use for purchases one time on the PayPal secure system. Once that is accomplished, you never again have to disclose your credit card information online. By paying with PayPal, you keep your credit card information private, meaning that you can shop without worrying about a hacker downloading your account data from your online merchant.
Relieve yourself of the embarrassment and hassle of trying to purchase goods and services online only to have your credit card declined. Because you can set up multiple bank accounts, debit cards, and credit cards to fund your PayPal account, you can rest assured that your PayPal purchases always go through the first time. PayPal will then look for funds from your sources based on the order you define.
