Here in southern New Jersey there is always a bit of a slowdown the first few weeks of September. That's because of schools being re-opened and everyone getting back to their usual routine. However, once things get back to nomal, we get busy and remain that way well into December.
I always do a newsletter mailing to my regular customers in September around the first day of Autumn. That helps to remind my customers that they need to start thinking about getting their vehicles cleaned, polished and waxed before the winter weather. I will also be mailing out reminder post cards on a weekly basis to my regulars during the months of October and November.
