When sales are slow, business owners have a tendency to cut back on all marketing expenses. Today, there are various ways of cost effective advertising to keep in contact with customers and prospects that might be considered. Talking to marketing consultants, reading books or searching on the internet are ways to find out what is working for others. There are direct mail campaigns such as postcards or coupon books. Internet advertising or email campaigns can hit directly at the target audience. Not communicating with customers and prospects will only hasten the sales slide and reduce the value of the business.
