:nixweiss I've never bothered and quite frankly, I am put off by their marketing attempts.
I get a call one day from them, saying it was very important to call them back. I knew I didn't have any unhappy customers but there is another detailing shop with a similar name whose owner I know writes bad checks (I get calls occasionally since the business names are similar and people making the calls are too stupid to notice the difference). Anyway, I call back and it was a damn sales pitch they threw at me. They said it was for a limited time and they'd only charge me $400 to join. I told them I wasn't interested and she said if I didn't join in the next 30 days, they would withdraw their offer to join.
6 months later, they called back, same tactic. :hairpull
