Two stores dominate the drive-up auto parts market in most US towns: AutoZone and Advance Auto Parts. Both test batteries for free, scan check engine lights and lend specialty tools, but the details differ in ways that matter when you are standing at the counter: how long you can keep a loaner tool, how many days you have to return a part, and what a rewards program is really worth.
Each guide below collects the store’s own published policies, with the date we checked and a link to the official page, so you can confirm anything before you rely on it.
The short version
| AutoZone | Advance Auto Parts | |
|---|---|---|
| Return window | Return an item in its original condition and packaging, with the receipt, within 90 days for a refund. Refunds may be denied if the item was used or installed; defective items are handled under the warranty.
