AND when you buy from me, you get a "LIFETIME SERVICE CONTRACT" in that if you have a question or problem, you email or telephone ME with your question and I try to answer it at that moment.  You are entitled to "value for your money," so that just as you would expect your retail store to "make good" on a purchase, I feel you are entitled to exactly the same thing.  When I can clear something up for you in a moment or two I want to do that because it doesn't make sense for you to struggle and wonder.
