I think that the Bosch non-premium line has been phased out in the US, though there may still be stock floating around.
The Bosch usa website used to describe both the standard and Bosch Premium oil filters, but now it only has the Bosch Premiums. There was also a time when Bosch Premium was only sold at Autozone, but that has changed as well.
The Kragen deal is a good one!
