Yep currently ~$6.99 everyday at AAP. But, don't feel like buying many, use code P20 online and take 20% off the top, with in store pick up. Buying more, other codes take 30-40% off, or combine with other things if you have a larger order.
Buy 4 P1's add a ~$2 filler, take $10 off $30 order with ES123 or similar.
Just a couple examples.
