Trying to attacted SS business. The younger crowd seems to go to near by larger town at a popular SS car wash, I guess its kind of a hang out place. My equipment is better,better chemical, price about the same. Thinking about adding bonus time. Currently my price is 1.25 for 3 min or .36 per min. I would like to have a 5.00 for 20 min option, but my timers will only let me add time after the start up. I am thinking about bonus time of 1 min per .25 after start up. Also having a sign that says 5.00 for 18 minutes. Will this help or hurt my SS business. Any other ideas?
