"All the stuff they overstocked for back-to-school (season) that didn't get purchased" is available after Labor Day at a discount, Mendelsohn says. In September, "I think you can save (another) 15 percent off back-to-school specials. They'll mark them down one last time."
Consumers can also find some "bundling" deals on technology in September after Labor Day. When you buy one gadget, such as a computer, the retailer might throw in something else, such as an MP3 player, for free, she says.
Some stores will accept their competitors' coupons, which helps to save a little extra money without burning extra gas.
Don't go to a department store, chain store or big-box retailer without at least checking the Internet ahead of time for coupons, Mendelsohn says. Just hit a search engine, type in the name of the store you want to visit and the words "coupon code," she says.
