The following text is for questions 29 to 31.

    With an overwhelming number of options on the market, shopping for appliances can be something of a headache-unless, of course, you go in with a plan. During the appliance scouting process you'll likely realize that brand new items are often outrageously priced, and begin to ask yourself, "Should I buy a refurbished appliance instead?" The short answer is: It depends. Whichever route you choose, consider these easy yet important refurbished appliance shopping tips, to ensure you're equipped to make the best decision for your home.

1. Check the warranty.

    This is the golden rule of appliance shopping. Warranty periods can be significantly shorter for refurbished appliances versus brand new appliances, but they shouldn't be too short. Be wary of any refurbished appliance with a short warranty period (less than 90 days), as it could be an indication that the product has limited longevity.

2. Look for floor models.

    Technically floor models aren't refurbished appliances since they've never been used or repaired, but sometimes they're sold at refurb prices. Given that floor models primarily function as selling tools, the variety can be relatively limited. However, with a little internet savvy you can usually find a few options from almost all major appliance brands on sale. Bear in mind that when a display item goes on sale, it usually means that the manufacturer has released newer versions-so do your due diligence to make sure you're not purchasing something.

3. Shop around.

    Now, because of the Internet, it's easier than ever to make sure you're getting the best deal on appliances, refurbished or otherwise. Compare prices on refurbished models from a handful of retailers with the cost of new appliances. Keep in mind that although shopping online is convenient-and there are certainly some good deals to be found therethe best way to purchase a refurbished appliance is to go into the store and visually inspect the item yourself.
