Labor Day is about more than barbecues and the beach. It’s also a great chance to take advantage of sales on stores’ summer merchandise as they attempt to clear the shelves before fall. Outdoor furniture, sports gear, lawn mowers, swimsuits, laptops and mattresses are among the best items to buy on Labor Day, according to DealNews.

This year, NerdWallet recommends staying at home instead of going to stores. You should check your favorite stores’ social media to make sure you see all of their discounts -- and do so early. Many retailers offer pre-Labor Day promotions with sweet sales.
