I find this very interesting

I am fortunate for the amazing professionals and specialists I have met over the years for every problem, repair, or concern I ever grapple with.  I have a great general doctor I have been seeing for 15 years now, a trustworthy and brilliant mechanic that keeps my cars running in perfect shape at unbeatable prices, and a home handyman for any fixes or repairs that exceed my own skills or expertise.  Just recently, I got even luckier when I found a great local heating and cooling supplier and repair service after a few years of jumping between various companies that all left something to be desired. My current company is a family run business that goes back three generations and has been trusted in the community for that entire four decade run.  Almost a quarter of the way into the 21st century and this heating and cooling company is still going strong. They offer this great loyalty program that utilizes punch cards like the ones you might find at sandwich shops, smoothie and coffee cafes, or even some bookstores. But I had never seen a punch card for anything related to home maintenance, let alone an HVAC supplier.  Everytime you schedule and pay for a routine maintenance call, you get one of the blocks punched which can be redeemed for $30 off a new system. Each card has five blocks which totals to $150 off a replacement HVAC system if you redeem the entire card at once. In just one year, I was able to get my discount on a fantastic new air conditioning system with a fully redeemed loyalty rewards card.
