The old-school door-to-door selling model still works. The reason we're still doing this is because of the benefits we get out of it, and it comes down to human psychology. I prefer to visit our products and get more new things for new products. People do like to be sold to, there's no doubt about that. They may not like the idea themselves, but they have a sense of humor about it and just need us to go over things again in order for them to know more about our product or service and how great we are at what we do.
