That is indeed an Expedit shelf. I think I spent a few dollars over $80 when I bought it. The nice thing is that the dividers act like shelf supports, with the shelf board going through from the left to the right of the whole shelf.This looks very similar to the IKEA shelf I use for most of my books. The model I have is the Expedit series. Very reasonably priced and the non-wide shelves help with shelf's strength under load.
