If you need new patio furniture, May is the best time to buy it. This is the time of year when stores unload discontinued models and items from the previous year. If you prefer the latest outdoor furnishings, donâ€™t worry. Some stores also discount new patio furniture to attract shoppers. Strapped for cash now? Another excellent time to buy is September. This month, you may also snag great deals on jewelry. Just avoid buying before Motherâ€™s Day.
