Why Sell Your Stuff?
First, let’s talk motivation. Maybe you’re looking to supplement your retirement income, save for a special trip, or just clear out the garage.

Selling your gently used items is a smart, eco-friendly way to give your belongings a second life—and put a little extra jingle in your pocket. Plus, with inflation and rising costs, every dollar counts.

  1. CardCash
    Best for: Unused Gift Cards
    We’ve all received a gift card to a store we never visit. Instead of letting it gather dust, CardCash lets you sell or trade your unwanted gift cards for up to 92% of their value. You can opt for cash (via check, direct deposit, or PayPal) or swap for a card you’ll actually use. Buyers get a 45-day guarantee, so it’s a win-win.

  2. Chairish
    Best for: Home Furnishings
    If you’re redecorating or downsizing, Chairish is the go-to for selling (and buying) unique furniture and decor. Listings are free (up to nine per month), and Chairish even helps with shipping those bulky items. Just note: they take a commission—up to 40%—so price accordingly.

  3. Craigslist
    Best for: Old-School Local Sales
    Craigslist is the granddaddy of online classifieds. You can list just about anything, from books to cars. Its massive user base means your listing gets seen, but beware: scams are common. Always meet in public and trust your gut.

  4. Decluttr
    Best for: Unused Tech
    Got an old phone, tablet, or stack of DVDs? Decluttr gives you an instant quote, pays for shipping, and sends your money via direct deposit or PayPal. They’ll refurbish or recycle your items, making it a green choice, too.



  5. eBay
    Best for: Auctions and Collectibles
    eBay’s auction-style platform is legendary. Whether you’re selling vintage baseball cards or last year’s smartphone, you can choose between auction or Buy It Now listings. Fees can reach up to 15.3%, so factor that in.

  6. eCampus
    Best for: College Textbooks
    Textbooks are pricey, but eCampus helps you recoup some costs. Sell your old books for cash or store credit (which gets you the best value). Free shipping and instant quotes make it easy.

  7. Facebook Marketplace
    Best for: Local Community Sales
    This one might surprise you! Facebook Marketplace is a favorite for buying and selling everything from lawnmowers to lamps. It’s integrated with your Facebook profile, so you can check out buyers and sellers before meeting. Just remember: always meet in a safe, public place.

  8. 5miles
    Best for: Local Sales with Extra Security
    5miles shows you items for sale nearby and lets users verify their identity with a phone number or Facebook profile. Ratings help weed out scammers, and you can find everything from cars to kitchen appliances.

  11. Poshmark
    Best for: Clothing and Accessories
    Poshmark is like a virtual closet sale. List your gently used clothes, bundle items for buyers, and join Posh Parties to boost your sales. Shipping is a breeze with prepaid labels, and payments are fast.

  12. The RealReal
    Best for: Designer and Luxury Goods
    If you have high-end items—think Chanel, Gucci, or fine art—The RealReal is your best bet. Their experts authenticate every item, and they handle the entire selling process for you. Commissions vary, but VIP sellers get the best rates.



  13. Stillwhite
    Best for: Wedding Dresses
    Why let your wedding dress gather dust? Stillwhite helps brides recoup some of that investment. Listings cost $25–$35, and the platform donates 1% of revenue to carbon removal, making it a sustainable choice.

  14. Swappa
    Best for: Verified Tech Sales
    Swappa is all about tech—phones, laptops, video games—and every listing is reviewed by real people. Transactions are via PayPal, and both buyers and sellers pay a 3% fee. Customer service is top-notch.

  15. ThredUp
    Best for: Consignment Clothing
    ThredUp is a leader in sustainable fashion. Request a Clean Out bag, fill it with clothes, and let ThredUp handle the rest. You can cash out or use store credit for even more savings.

Tips for Safe and Successful Buying & Selling
  • Meet in Public: Always meet buyers or sellers in a well-lit, public place. Many police stations offer “safe exchange zones.”
  • Bring a Friend: If you’re meeting someone you don’t know, bring a buddy along.
  • Trust Your Instincts: If something feels off, walk away.
  • Research Prices: Check what similar items are selling for so you don’t get shortchanged—or overpay.
  • Understand Fees: Each platform has its own fee structure. Read the fine print so you know what to expect.
  • Protect Your Info: Never share unnecessary personal details. Use in-app messaging and secure payment methods.
