We’ve been careful to select only those vendors we’ve used in our own business, either as a part of a client project or as a means to promote our own business. We are well aware there are many, many competing suppliers who compete with—and may even be better providers than—those we’ve chosen to feature. The vendors you see in the online Marketing-Playbook.com site and in the printed Marketing Playbook are those who have stood the test of time for us and our clients.
