Have you watched "Kitchen Nightmares" on TV?
Now don't take me the wrong way! What I am getting at is there are many clever ideas to advertise your business that cost little or no money. About half the shows have Ramsey setting up some kind of promotion to bring in a lot of new business to an old establised place that (usually) the customers have already decided is no good. So if the part of the "common business strategy" that you worry about is advertising budget, then give it a look.
