Buybrakes vs carid vs...?

So in the market for some new brakes. Not looking for anything fancy, so I’m looking at the centric premium kit. But there is a huge price difference between these 2 sites. Not sure how there can be that much disparity. Am I missing something obvious?

 

I would guess that BuyBrakes has it listed incorrectly on their site, I have never found them to be very competitive on pricing either. Adding up all the items in the kit on RockAuto is $270.74, so the carid prices seems correct.

Front Pack - 909.44051 - (1 x 105.13030 Pads and 2 x 120.44156 Discs)
Rear Pack - 909.44523 - (1 x 105.13040 Pads and 2 x 120.44157 Discs

 

I appreciate the feedback! I would say something can’t be right with buybrakes. Ordered from carid last night and already got a notice for delivery tomorrow.
