Got Black Friday?

137.4 million Americans do this year - that's the number of shoppers who'll be out and about on Thanksgiving weekend looking for their share of deals and steals, according to the National Retail Federation.

But there's no rule that says you have to only spend money on Black Friday; you can make some cash, too.

There are myriad ways to make money selling your own goods online this week and into the holiday season - even unwanted items like old cell phones, games and other gadgets.

Consider, an online site where you can sell compact discs, DVD's, video games and more. DeCluttr is offering an extra 10% on all trade-ins starting Thanksgiving at 6 a.m. and ending Cyber Monday at 11:59 p.m. "You might just make enough money to cover some of your Black Friday shopping," the company says in an email to TheStreet.

Decluttr says you can make up to $550 selling a Surface Pro 3 or $465 for your iPhone 7. Or, sell an Xbox for $140 or $28 for a Madden BFL 17.

Or, try selling your old computer on Stopoint, a Miami-based online selling service.

"Stopoint offers an easy way to sell old unwanted technology, keep them it out of landfills and produce cash within 24 hours," the company states in an email to TheStreet. allows sellers to tout high-end electronics such as MacBooks, tablets, and cellphones, with a user-friendly select-ship-and pay system. "When you sell to a trade-in program such as Stopoint, you can be sure that old electronics will be bought, as long as they are in decent working condition and match your description of it," a company spokesperson states. "There are no back and forth conversations with the buyer and potentially creepy interactions with strangers or online scammers. The whole experience is pretty much hassle free."

Stopoint pays within 24 hours on PayPal or gives customers an option to receive a check within three days after the product receipt. "In addition, we offer a price-match program called MATCH5 that allows them to pay a customer $5 more for an offer found on a competitor's site that is higher than ours," the spokesperson says.

From a selling standpoint, consumers who like to move products online say the Thanksgiving holidays may be the best week of the year to do so.

"I've sold many of my personal unwanted items during the holidays on eBay, Craigslist, and apps like Letgo, and Close5," says Alex Gaber, a certified eBay-expert based n New York, N.Y. "Over the years we've seen a great surge in sales starting Thanksgiving eve and until the day after Cyber Monday."

Gaber says he and his wife are avid gadget aficionados, and they'll use the money earned by selling products through Thanksgiving weekend and turn around and "take advantage of the discounts" on Cyber Monday.

The best sites to sell your stuff start with the big boys. Amazon, Craigslist, eBay, and Facebook all over a wide audience for that smartphone, 10-speed bike, or antique coffee table. But there are other sites that specialize in the exact item you want to sell.

For instance, Swappa specializes in mobile phones and tablets, while Bonanza was recently voted as the one of the sales markets' best alternative to eBay. Or, try AuctionFire, which only costs a $3.00 verification fee to join up. If you're into arts and crafts, Etsy has developed one of the most loyal followings in that niche in the U.S.

Many of these online selling sites are really coming on strong. Etsy, for example, recently reported 33% revenue growth for the third quarter of 2016. "Our third quarter results reflect the strength of our markets that connect people around the world and our seller services platform that is specifically focused on helping creative entrepreneurs start, scale and manage their businesses," notes Chad Dickerson, CEO of Brooklyn, N.Y.-based Etsy.

There's really no shortage of online sites to sell your personal goods this holiday weekend.

After all, when Americans are in a buying mood, the time to pounce is right now.
