Best websites to sell items online locally for any category​

These platforms are perfect for clearing out your home, selling general goods, and connecting directly with local buyers. They’re fantastic for anyone just starting out or testing the waters of online selling.

1. Gumtree

Best for: Selling almost anything locally, from furniture and electronics to cars and services.

Seller fees: Free to post ads in most categories. You can pay for features to boost your ad's visibility.

How it works: A true British classifieds institution, Gumtree is the go-to for local buying and selling. Simply create an account, post an ad with photos, a description, and your price, and wait for buyers in your area to get in touch.

Pros:

• Huge, established UK audience means your items get seen by plenty of local buyers.

• A wide range of categories lets you sell everything in one place.

• Direct messaging keeps communication simple and contained within the platform.

Cons:

• The platform's design is more basic compared to modern apps.

• As with any classifieds site, you need to be cautious and arrange safe meetups.

Tips for selling on Gumtree:

• Be descriptive. Use keywords like the brand, model, and condition of the product in your title to appear in more searches.

• Buyers on Gumtree love a good deal, so price your item slightly higher to leave room for negotiation.

2. Facebook Marketplace

​

Best for: Second-hand furniture, baby gear, clothes, and other household items.

Seller fees: It’s free to list and sell items for local collection. If you offer postage and use Facebook’s payment system, a selling fee applies.

How it works: Since it's integrated with Facebook, listing is incredibly simple. Go to the Marketplace section, create a listing with photos and details, and it will be visible to users in your local area. Buyers will message you directly through Facebook Messenger.​

Pros:

• Massive built-in audience of Facebook users.

• You can check the buyer's profile, which adds a layer of confidence.

• Unlimited free listings for everyone.

Cons:

• Seller protection is limited for cash-in-hand transactions.

• Be prepared for plenty of messages and some haggling.

Tips for selling on Facebook Marketplace:

• Join local "for sale" groups and share your listing there for extra visibility.

• For safety, always meet buyers in a public place.

​

3. Shpock

Best for: A mobile-first experience for selling a wide variety of second-hand goods.

Seller fees: Free to list. If you sell using buyer protection (which includes postage), a small fee is taken from the final sale price.

How it works: Shpock stands for "Shop in your Pocket," and it's designed to be quick and easy. Just snap a few photos on your mobile, add a title, description, and price, and your listing is live. Buyers can make an offer or buy instantly.

Pros:

• The app is very user-friendly and intuitive.

• Offers secure delivery options with integrated couriers like Evri.

• Buyer and seller protection is available for posted items.

Cons:

• The free discovery feed can be very busy, so paying for boosts might be necessary for items to stand out.

Tips for selling on Shpock:

• Good photos are essential on a visual-first platform like Shpock. Use natural light and show the item from all angles.

• Respond to questions and offers quickly to keep potential buyers interested.

​

4. Nextdoor

Best for: Selling or giving away household items to people living in your immediate neighbourhood.

Seller fees: Completely free.

How it works: Nextdoor is a social network for your neighbourhood. Its "For Sale & Free" section lets you post items that only verified neighbours can see and respond to. It’s built on community trust.​

Pros:

• You keep 100% of what you earn.

• Generally safe, as you’re dealing with people in your local community.

• Perfect for items that are too bulky to post, like garden furniture or large toys.

Cons:

• Your audience is much smaller than on larger marketplaces.

• Strictly for personal sales – businesses and frequent resellers are discouraged.

Tips for selling on Nextdoor:

• Be friendly and build a good reputation. You’re selling to your neighbours, after all.

• Use the discount feature if your item hasn't sold after a couple of days to bump it up in the feed.

​

Best for fashion and clothing

If your wardrobe is overflowing, these niche marketplaces are designed to help you find buyers who share your style. They attract a targeted audience, meaning your items can sell faster and for a better price.

5. Vinted

Best for: Selling pre-owned high street and designer clothing, shoes, and accessories.

Seller fees: It’s 100% free for sellers. The buyer pays a small "Buyer Protection" fee and postage costs.

How it works: List your item on the Vinted app with photos, a description, and a price. When someone buys it, Vinted provides you with a pre-paid postage label. Just print it, pack your item, and drop it at a local parcel shop. Once the buyer confirms they’ve received it, the money goes into your Vinted Wallet.

Pros:

• You keep every penny of your asking price.

• The postage process is incredibly simple and hassle-free.

• A huge community of fashion lovers means popular brands sell very quickly.

Cons:

• Primarily for personal sellers, not commercial businesses.

• No option for local collection – all sales must be posted.

​
Tips for selling on Vinted:

• Activate bundle discounts in your settings. This encourages buyers to purchase multiple items at once to save on postage.

• Be active on the app. "Bumping" your items (a paid feature) or re-listing them can get them seen by more people.

6. Depop

Best for: Selling vintage, unique, and trendy fashion items to a younger, style-conscious audience.

Seller fees: Free to list items, but Depop takes a 10% fee from the total transaction value (including postage) once an item sells. There are also standard transaction fees from PayPal or Depop Payments.

How it works: Depop feels like a mix of Instagram and eBay. You create a profile, list your items with cool, stylised photos, and build a following. Buyers can like your items, message you, and purchase directly through the app.

Pros:

• A strong community lets you build a brand and attract repeat customers.

• Excellent for niche styles, vintage finds, and streetwear.

• You can arrange your own postage or use Depop's integrated shipping options.

​
Cons:

• The 10% selling fee is higher than some alternatives.

• Success often requires creating a strong visual aesthetic and being active in the community.

​
Tips for selling on Depop:

• Your photos are everything. Model the clothes yourself or create flat-lay images with a consistent background to build a strong brand look.

• Use relevant hashtags and detailed descriptions so buyers can find your items.

​

7. eBay

​Best for: Reaching a massive audience for almost any item, from collectibles and electronics to fashion.

Seller fees: Private sellers get up to 300 free listings per month. For most domestic sales, eBay does not charge a final value fee. Fees only apply if you exceed your free listings, add optional upgrades, sell internationally, or list in certain categories like vehicles.

How it works: As the original online marketplace, eBay is a powerhouse. You can list items as an auction or with a fixed price. When an item sells, you arrange postage and send it to the buyer.

Pros:

• Unrivalled global audience gives you the best chance of finding a buyer.

• Strong seller protection policies.

• Great for discovering the market value of unusual or collectible items via the auction format.

​
Cons:

• The fee structure can feel complex compared to simpler platforms.

• High competition means your listings need to be well-priced and optimised to stand out.

Tips for selling on eBay:

• Research sold listings to see what similar items have sold for. This helps you price competitively.

• Offer free postage and factor the cost into your asking price. Buyers are often more attracted to listings with free delivery.

Choosing the right free selling platform: Which one to pick?

The best choice depends on what you’re selling and how you want to run your business. Here’s a quick comparison of the free online selling platforms UK to help you decide.

​

Smart selling tips for success

No matter which platform you choose, follow these tips to make your items stand out on these popular selling sites.

1. Write listings that sell​

Your title is key. Be specific and include the brand, size, colour, and condition. Take at least three to five clear photos in good, natural light. Show any flaws or details up close. Keep your descriptions short, factual, and SEO-friendly – buyers want the key information quickly.

2. Price your items right​

Look at what similar items have sold for to get a sense of the market value. Price your items a little higher than your minimum to leave room for offers without losing out. Using prices like £19.99 can feel more appealing to a buyer than a flat £20.

3. Handle postage and safety like a pro​

For local meetups, always choose a busy public place, like a high-street coffee shop or a supermarket car park. When posting items, use sturdy packaging and send them promptly via a reliable service like Royal Mail. On many sites, quick dispatch is key to a good seller rating.

Tired of packing boxes and queueing at the post office? With Printful, you can create and sell custom products like t-shirts, hoodies, and tote bags with your own designs. Just add them to your online store, and we’ll print, pack, and post every order for you – straight from our UK fulfilment centre to your customer.
