5 Marketplaces to Sell Your Stuff: What to Do with Your Declutter

With the recent popularity of people like Marie Kondo and The Minimalists, people are realizing that maybe they don’t need quite so much stuff. And in fact, they may be happier with a little less.  

Now, it’s time to figure out what to do with it all! Where can you turn to give your old things a new life — and make a little cash in the process?  

You probably know about Craigslist, but the interface is clunky and it lacks a mobile app. Facebook Marketplace works well, but what about those of us trying to declutter our social media lives as well as our homes?

Luckily, we’re living in the golden age of online selling. There are dozens of services out there devoted to relieving people of their unwanted stuff. 

Here are five top picks you should consider!


Nextdoor is a neighborhood app that requires users to verify their addresses before they can join. Your network on Nextdoor is entirely local, meaning no one from outside your immediate area will be able to see your posts. 

Nextdoor can be a mixed bag — it’s great for finding lost pets or learning more about your quirky neighbors. But there are also paranoid retirees who think the water meter guy is casing houses. 

Still, one of their great features is their For Sale section. Since the app is all local, you can sell items to people in your area. This makes pickup or dropoff much easier than a city-wide platform. 

And as a bonus, you can meet more of your neighbors!


decluttr removes the guesswork from selling your old cell phones, tech, textbooks, Blu-Rays, video games, and LEGOs. No need for posting pictures, negotiating with sellers and arranging the hand-off. Instead, decluttr buys your items from you directly.  

For tech items, you just find the make and model of what you’re selling and describe the item’s condition. decluttr will offer you a price and provide a pre-paid shipping label so you can mail in the item.

Media with bar codes, like CDs, DVDs, Blu-Rays, and video games can all be scanned with the app for a quick quote as well. Once decluttr has received your items, you’ll get paid by direct deposit or Paypal! decluttr then refurbishes items (if necessary) and resells them, keeping them out of your home and out of landfills.

And if Junior has outgrown his massive LEGO collection, decluttr will also buy those old bricks for $1.00 per pound.


OfferUp is another great way to sell items, either in your area or further away. What makes it stand out from the rest is its focus on safety and accountability. 

Unlike Craigslist’s anonymous structure, OfferUp users must create a profile. Their identities are then verified using their Facebook profile, phone number, and email address. Users are rated based on their transactions, so you will know if the person you’re selling to is reliable.  

OfferUp also provides community meetup spots for in-person cash purchases. These are well-lit, public places with video cameras — often police stations or local businesses. So you can sell your items in a way that makes both buyer and seller feel safe.

There is a shipping option with OfferUp as well. Payment is completed through the app, and the funds are released to the seller within a week of the buyer receiving the item.  This shipping option is great if you have some odd or niche items that you’d like to offer to a larger market than your immediate area.


If you used to be Yves St. Laurent, but now you’re more yoga pants, Poshmark may be the place for you. 

Poshmark is a buying and selling platform strictly for clothes, accessories, and unused makeup. (No perfumes or nail polish, as those can’t be shipped through the mail.) 

All aspects of the transaction are completed through the app, from posting items to payment. Buyers and sellers have the protection of the app to make sure that buyers get their goods and sellers get paid.

Payments will stay in the app until the user decides to make a transfer. At that point, they can transfer their earnings to their bank, or request a check.

A bonus with Poshmark is that buyers have an extra layer of protection when purchasing high-end items. If a designer item sells for over $500, it is shipped to Poshmark’s headquarters for authentication before it’s forwarded on to the buyer. With that assurance, buyers can be comfortable buying high-ticket items. Handy if you have a bunch of great-grandma’s old furs or a boutique wedding dress lying around!


5Miles is a buying and selling app limited to the people within five miles of your current location. Like OfferUp, 5Miles provides user authentication and a rating system, so you know who you’re dealing with and how reliable they are.

5Miles uses your phone’s GPS to determine your location and allows buyers to sort for items based on location. Sales are quick and convenient since everyone who sees your item is so close by. 

5Miles also has a Safe Exchange Area Locator (SEAL), providing secure and monitored places for exchanges. Sales can be completed in cash, or through the 5Miles app and shipped.

These online marketplaces are great for connecting the right seller with the right buyer. Gone are the days of putting a sign in the yard for your garage sale, and hoping that few people who see it will want your stuff. 

Our re-selling market has gone national, and can even be global on platforms like eBay. So you have no excuses for hanging on to all those unwanted treasures. Share them with the world — and then buy yourself something nice.
