The best way to save money is to shop smart, and that often involves staying on the lookout for new sales, coupons, and promotions. Many of my groceries are bought as “buy one, get one free” deals at one of my favorite local grocery stores. They even have a separate sales ad at the front of their stores near the shopping carts that contain all of that week’s sales and specials, making it easy to scan deals for all items in the store at once. This prevents having to wander aisles endlessly, hoping that you’re finding what you’re looking for. I also try to buy used items when I can, like my vehicles and cell phones, the latter of which I buy as factory refurbished devices that in my opinion are as good as brand new. There are also smart ways to shop for heating and cooling system equipment, parts, and accessories. The hardest time of the year to get a replacement air conditioner, or even to buy AC parts, is the dead middle of summer. This is when air conditioning is at its highest demand, limiting available supplies. The same goes for trying to buy a furnace in winter, it’s probably not the best idea if you aren’t suddenly facing an immediate crisis and can’t wait a few months to get a much better deal. I bought my furnace in late spring last year and got a new system that was being clearanced out in preparation for the upcoming new model from that particular manufacturer. I essentially paid 40% less than I would have if I hadn’t been smart about when I purchased my heating system equipment.
