When looking for a treadmill, you will need to decide if you want to purchase a used treadmill or a new treadmill. If you are interested in purchasing a used treadmill, you can check your local newspaper, under the fitness/sports equipment for sale category, to find local people selling used treadmills. If you would prefer to purchase a new treadmill, you can look through the sale ads in your Sunday paper or you can go to store websites (i.e. Sears.com) for information and pricing.
