So, you want to save some money this month and get a great deal? Go Banking Rates has a list of the best and worst things to buy this month.

Start by thinking big -- as in big screen TVs. Some stores have leftovers from last year and Super Bowl sales. They're looking to sell them to make space for the latest and greatest technology that's hitting the market.

Maybe you're more into working out? No sweat. You can run into great deals on exercise equipment right now, too. You could save as much as a few hundred bucks on a treadmill or elliptical.

After that workout, you want to eat healthy, right? Check the frozen food aisle for veggies and more. March is National Frozen Food Month and there are coupons galore to celebrate.

Meanwhile, here are a few things you want to avoid buying -- if you can.

Need a new car? You'll struggle to drive off with a great deal. New models are driving onto dealers' lots and older ones won't get to a good sale until at least August.

Finally, there are smartphones. If you're smart, you'll wait until the new models are out later this year. You can either get those or save some cash and get the cheaper, older model.
