I was asked to test a new photobook product for saal-digital. The interface was really simple, the product really well made and affordable (28 image A4 hardcover for under £40 including delivery). The big selling point of these photobooks, as well as the accessibility of design, is that you can share the online preview with others and they can order directly, you can also embed the online preview too.
In a blinding display of German efficiency, though I ordered the product at about midnight, it was physically dispatched by lunchtime the next day. Highly recommended!
