PayPal has initiated a new feature that allows customers to purchase from your site without requiring the purchaser to have a PayPal account.
For blogs that wish to sell items, this is a big improvement. The way it worked before, if someone wanted to buy something from your site, they would have to sign up for a PayPal account. This was a killer in many circumstances since buyers did not want to go to the trouble.
At Blogger Forum we have a coffee mug with the Blogger Forum logo. We probably would never have bothered trying to sell the things since the cost of merchant credit card accounts are prohibitive if you're selling a $6.95 item. With the new PayPal system, the purchaser simply uses their credit card. See the PayPal site for details.
