Each day, more businesses are drawn to the promise of increased access to customers, combined with dramatic cost reductions. However, consumer expectations and demands seem to increase daily. The major challenge in building successful Internet commerce sites continues to be how to use Internet technology most effectively to deliver added value to customers.
