Hi, I'm Mark Calvert. For the better part of 3 decades, I've been a semi-locally professional musician. For the past 3 years I've been making a supplemental income reviewing products and services online. I only review products and services I've actually purchased and used, and I never endorse a product unless my expectations are met. Calcopromo offers: Promotional - Buttons, T Shirts, Caps, ... Online Guitar Lessons, and various brands of Electronic Cigarettes.
