Plain-language guides for buying and replacing common parts yourself, using the prices and policies we checked at AutoZone and Advance Auto Parts. Each guide links to the official sources it relies on.
Start with the guide for the job in front of you. If your car will not start, read how to choose a car battery and the cheapest car battery guide, then use the free battery testing at either store before you buy. If your brakes squeal or grind, the brake pad cost guide explains the parts, tools and when a shop is the better call. The brand comparisons answer the question we hear most at the counter: is the store brand at one chain the same as the store brand at the other?
