Me neither, and agreed on AZ being "more miserly than AAP." That said, I've noted that latest AAP 15% off promos looks to have upped the minimum purchase from $35 to $50. But, for now at least seems free ship still at $35+. Not too long ago could snag a 15% discount no minimum, but seems those days gone.I have not really followed AutoZone much anymore unless it is just an outright clearance. They seem to be a bit more miserly than AAP when it comes to discounts and thresholds needed for them.
