It does not surprise me that Amazon will terminate their relationship with BillMeLater. If you recall back in October eBay purchased BillMeLater. With eBay as the new owner, they would have access to information Amazon would not want their noses in.
I have mixed emotions of Amazon not offering BillMeLater. When Amazon initially offered BillMeLater, I ran campaigns promoting the service. My sales nearly doubled that week alone. Buyers calling asking for details about BillMeLater. eBay has too much and Monopoly is what comes to mind.
This is a big year for eCommerce as well. You will find Google Checkout becoming more popular and eCrater stronger and more popular. This is a great time to sell or start selling online. You have options and many of them. Some requiring a small investment and other absolutely Free.
