The entire Sony e-commerce network is shutting down today and by September 30th 2015 it will be deleted. This will result in Sony being unable to directly sell products, such as the Sony Digital Paper. This is not the end of the world for people who want to buy this device though, Sony has setup a new marketing site that heavily leans on 3rd party re-sellers to fill the void.
I talked to a number of high ranking executives in charge of the Sony Digital Paper today and they informed me that a new marketing site has been developed. It replaces the old product landing page and has new pictures, videos and links to all of their official partners where you can purchase a DPT-S1. I would recommend using B&H Photo, who will sell to the general public in the US. Their inventory shows that it is on pre-order right now, but I have been assured that they will get their shipment within the next week. Sony’s other retailing partners are highly specialized in the medical or legal fields and will only sell the product within those industries.
Sony has also confirmed with Good e-Reader that they will continue to provide customer support for their online partners. So if you purchase a Digital Paper from B&H Photos and have a problem, you will contact the Sony guys via email or call them at 877-723-7669.
