I was browsing at AAP this afternoon, and, of course, stopped by the oil filters. The standard Purolator red can (5000 mile rated replacement for the Classic) was $6.49! This makes them about as expensive as a Wix/Napa Gold (the same price as the Napa Gold, and only 50 cents cheaper than the Wix!) This was the cheapest non-OEM filter they had on the shelf! I passed on them.
