They don't limit how many times you can bring the pads back? They pulled that shit on me when I lived in Pa.
not at autozone in California, the lifetime warranty law vary's from state to state, never had a problem swapping anything at autozone as long as it shows it as a purchase on my account
Warranties - AutoZone Limited Warranty (United States Only)
If a part fails during the warranty period shown on your receipt, bring the part to any AutoZone store and you will receive a replacement or refund. Warranty excludes damage caused by misuse, abuse, other faulty parts, improper installation or off-road, commercial or marine use. Warranties on replacement parts cover the unused portion of the original warranty or 90 days, whichever is longer. Warranties expire when you sell your vehicle.
I always buy the "lifetime warranty" parts so my receipt shows "lifetime warranty"-for as long as I own the vehicle"
it does not state you can only have 1 exchange or 2 nor any other number, it says: "if the parts fails during the warranty period"
