Wonder if the Costco results are tied to inventory.....might omit products that are out of stock? I know, generally, there's a shortage of car batteries in the market right now. Cold snap in the West drained inventories and it's taking longer than usual to replenish.
As for me, I spent 1/2 day yesterday freezing my balls off outside changing both front hub assemblies on the Escalade (speed sensor in one of them was bad and was activating the trac control randomly). Hubs were freebies from work (mismatched brands, but meh).....but I feel like the sub-zero (it was hovering around -6) labor more than paid for it, lol. Glad I did though, with the big snow today, we need it.
