Yes I am, but Costco isn't such an exclusive club. You might have to order and pay online to get this price. I doubt they keep such an odd size in stock at the local Costo's. And then the in-store pricing via special order might be closer to retail. That's my guess anyways.

Our local Costco currently has $80 off when you buy 4 tires. I wonder if you can get the discount if you present the online receipt. Then you could get 4 rear PS2's for $96 each.
