You can use PayPal, Google Checkout and, Authorize.net (credit card) to shop at this site. All purchases are secure.
Here's how it works: You find an item you'd like to purchase. You use one of the above methods for payment. If you were to use, let's say Visa, first Visa gets notice "Give MrBalleng "X" amount of money for my order". Visa then transfers the amount to MrBallenG. MrBallenG sends your order.
The process is the same for each type of payment. Since there's a "middle man" this website does not get access to the information you use for your means of payment. The payment page is a secure link which only you get to see. And to make sure, you can check for the little "lock" symbol in the web url bar as you place your order.
