So you’ve got yourself an Amazon addiction, shopping for everything from books to mobile phones to toiletries and myriad other odds and ends. Or maybe you want to shop the retailer, but are no fan of sending credit card information across the Web for phishers to scavenge. Or maybe you don’t have plastic on hand. In any case, you prefer to make your trades IOU-style.

Now you may. Amazon today has introduced to its many millions of annual customers the option to receive an invoice for goods received to be paid post-shipment. The megasite has signed a deal with Bill Me Later to reach the check-writing demographic, a group undoubtedly decreasing in size but still adamant in its preference for a more tangible transaction, so to speak. The public’s trust in e-commerce may have grown quite a bit in the last decade or so, but holdouts evidently exist.

This isn’t the first we’ve heard of ties made between Amazon and Bill Me Later. Late last year, the retailer was reported as having invested in the alternative payment system. But for many shoppers the news today of the arrival of Bill Me Later as a payment choice on the storefront has likely come not a moment too soon. Bill Me Later, founded in 2000, has come to serve consumer needs on some 900+ sites big and small. It’s presumably safe to say many expected Amazon to make such a move years ago.
