Another option is to just add it to your insurance policy. State Farm for me.
You just call up any tow company you want and they direct bill your insurance.
In fact just used it yesterday for my old '77 truck....it broke down at home. Left the key in the cup holder and called it in from the office. They towed it in while I was at work to the automotive place. allowing me to work 12 hours without worrying about it. My agent will approve the $$.
I've heard to many horror stories about AAA towing to never use them again. When I used them as a college student it was horrible. Not all tow companies want to deal with AAA....
