I mostly see automotive, electronic retail, some internet and phone shops and some decent restaurant shops that do not pay a shop fee. I've done over 60 shops with them and I really like them, I just wish they could get better clients. My husband has a truck that we use for the oil change/tire rotation shops, but they are cracking down on getting the oil changed too often, saying that the dealership might refuse to do the work since it hasn't been long enough. I think that warning is probably meant for those with factory maintenance still in play. For us, we're way over that so if we want an oil change, we pay for it.
