Of course, many of these deals aim to make a buck by bringing customers in their stores. Before you show up at their doors, make sure you read the fine print and note limitations and restrictions at the business near you. If you're careful, you could score a decent deal on items like food and back-to-school supplies.
Regina Conway, consumer expert with SlickDeals, said Labor Day is an end-of-season sale, which is why summer items will be slashed dramatically.
"It's a good time to stock up on summer clothing, grills and grilling accessories," she said, noting that that some stores keep about 20 percent of their grill inventory throughout the year, so prices may go down later in the season. But buying a grill now allows you to tap into a greater inventory and still enjoy the benefits of the grill for the remainder of the season, she said.
Other deals, but not necessarily freebies, include outdoor items, hiking equipment and home improvement.
