1. Buy used, pay cash
Even if you pay the exact same price for two items, if you buy it on credit, you could end up spending double the price, depending on how long you take to pay it off. On the other hand, if you look online and find someone in your area selling the same item on a site like Craigslist or OfferUP, you can sometimes pay half the price of retail or less. Better yet, you can often find things you might need for free on Freecycle. Check to see if there is a local Freecycle group in your area.
