sorry about that ,i see your email today and ill call you tonight ,i know it sounds like an excuse but guys please realize i m a solo shop and do my best to get back wit ha response in a timely manner which sounds easy but if your trying to run a business (some of these single cylinders can take 8 hours per jug ) phone conversations and sometimes 20+ emails daily all with paragraphs full of involved questions about pricing setups and gains i can get backlogged. also keep in mind sometimes my spam blocker on my website contact page will accidentally delete questionable things in my inbox some of which could be legitimate customers ,probably the easiest way is if you have trouble please pm me and ill get back as soon as possible i will make it worth your trouble,thanks for your understanding
