Not sure. The retail drive is a external device, which would cost more. But the price seems about right for OEM. Just bought an OEM NEC for about the same price. All you get is the drive, you have to buy separately any burning software you want.
Just Checked site again and it was bulk. O.K. not only that the drive I purchased was DV-W58G-A95/A38 I presumed it was the DV-W58GA. which was not shown at that time my mistake for an extra £2 I could have got the better drive.
