I got the same message from BTD and ordered ONE 28mm tire a couple of hours ago. I flatted last Wednesday, huge chunk of glass causing a significant casing cut; put a boot on it and decided not to ride that bike far until someone had a sale on GP5000's. So, a good day for me to see this and I had not realized I had "bonus points" so $26 out the door including shipping.
