September marks the official end of summer.

But having just days left outdoors before the temperatures cool down means retailers are offering deals on bikes, lawn mowers and other gear you probably won’t need in a few months. Buying some of these things now — at a discount — can give you a chance to save money and stock up for next summer.

For some of these items, promotions will peak on Labor Day, but low prices and sales should still be found beyond the holiday. Here are five items to look out for this month.

Bicycles and outdoor gear. Retailers are looking to clear their shelves of the bikes, basketballs and other outdoor gear that consumers may have little need for once winter arrives, says Mandy Walker, senior project editor for ConsumerReports.org. It should be typical to see discounts of 20 percent to 40 percent this month, Walker says. For instance, Sears was offering discounts of 10 percent to 25 percent off some bikes this week.

Lawn mower and other tools. In a few weeks, you’ll be more worried about raking leaves than cutting the grass. Aware of that, some major retailers are lowering prices on lawn mowers and tractors, Walker says. Before heading to the store, do some preliminary research to figure out what type of mower is best for your lawn. Some styles may work well on hilly lawns while a yard with steeper climbs may require another type of machine, she says. Another tip: While we’re still weeks away from seeing regular snow, some stores are also discounting snow blowers now as a way to clear space for next year’s models, Walker adds.

Kitchen appliances. Now that the kids are back in school, some families are focusing on getting their homes ready for the holidays. Stores are trying to lure parents in the door with sales on home decor, kitchen appliances and other home goods they’ll need once the guests start to arrive. “It’s that big run-up to preparing for the big feast,” says Brian Hoyt, a spokesman for RetailMeNot, a digital promotion Web site.

If you need to replace your dishwasher or another large appliance before Thanksgiving, some retailers like Sears and Best Buy are offering discounts now of 30 percent to 50 percent.

Mattresses. After Memorial Day, September is the next best time of the year to buy a mattress, Glaser says. Some retailers are offering deals of up to 60 percent, just as generous as the ones they are likely to offer in the spring, he says. For instance, Sears is promoting a Labor Day sale that includes discounts of up to 60 percent off on queen mattresses. Bed Bath & Beyond is offering up to $300 off select Serta mattresses until Sept. 14. And Macy’s has a Labor Day sale that includes zero-interest financing on purchases of $499 or greater. So if your guest room is missing a bed, now might be the time to take care of that.

Clothing. Apparel sales in September aren’t only limited to parents sending kids back to school. As summer winds down, look for discounts on warm-weather clothing such as swim gear, shorts and sandals. High-end retailers also introduce steep discounts Labor Day weekend on a wider range of clothing. For instance, Neiman Marcus is offering up to 65 percent off certain apparel until Labor Day. Calvin Klein is offering 25 percent off of the entire site until the holiday. In the past, clothing has made up 35 percent of all Labor Day promotions, according to DealNews, so look out for more of those deals now.
