Did you know that some auto parts stores offer cheap or even free services, such as reading computer codes for diagnostics or even loaning out tools in some cases? I didn't even know this was a thing before, but the last time we stopped at an automotive supply, stuff like this was being advertised in posters on the windows. Next time your car needs something, you might just get lucky and find some free help from your local automotive supplier. It certainly can't hurt to ask. Some auto stores even have membership clubs that offer even more benefits as well as other ways to save money.
