My local store has had the brakes and rotors for a while now, but they just recently started stocking CarQuest transmission fluid and other items. Probably more items in there too, but I was in a hurry, so I did not look around much.
Yes offering the CarQuest red with the lower tier oil change specials would be a good move with the option to upgrade to the blue or what ever for a couple more bucks. On the other hand, that would probably put Purolator classic and the CarQuest red in a price war. Purolator brand is huge in terms of sales, so it probably is not going to happen any time soon. The majority of filters on the shelves were Purolator classic.
