I have two NuStar Comets (touchless) that are popular with tri-foam, rocker panel blaster and spot free rinse and blowers at two different self serve locations with a fairly large Express Wash with free Vacs opening a mile away near entrance to Walmart Supercenter. Anyone have any ideas on adjustments, marketing ideas, etc. to compete effectively. I am in a town of 25,000 population. My washes are 4$,$5,$6,$7. I expect they will price at $5, $7 and $9. Any advice would be appreciated
