I really enjoyed all of this learning the POS system and wish it could have continued. Even though I am retired, I have thought of a lot of things that these lessons would be able to help me with and learn more about. The best part is that just because a lesson is designed for one purpose, there are many other uses that it can be used for. The more I get into this, the more I learn the importance of these lessons to create new doors and openings for you.
