There was (and probably IS today) a website that will help product sellers to place on their website an alternative payment to paypal under the form of book buying (and other stuff) ... in other words the buyer would have an option to get the product by either paying fori it through paypal, or to pay for it by buying another book from a payment processor similar to payapl. I wonder if you can remember/know the website that has this option i'm talking about
There are so many web sites where you can buy or sell product and pay or get payment via PayPal, MoneyBooker or like these payment method. You can search and choose one of theme from Google. Best of Luck
