(Pocket-lint) - Facebook took on Etsy and Ebay four years ago with the launch of Marketplace, a feature within the main Facebook app that you can use to buy and sell goods.

We've seen it work really well on a local basis because it's so simple to see free and paid-for items that are around where you live - and around the stuff you're interested in. 

Previously people used Facebook Groups to buy, sell, trade, and barter. You could set up a garage sale-type group for your community, for instance, so that people in your local neighborhood can post things they have for sale and look for items from others. But it was a bit clunky. 

Here's everything you need to know about Facebook Marketplace, including where to find it.

Where can you find Marketplace?


Simply tap on the Marketplace icon at the bottom of the Facebook app.

How can you browse items for sale?

Marketplace opens with photos of items that people near you have listed for sale. To find something specific, you can enter a keyword in search at the top and filter your results by location, category, or price. Next to the search icon, you'll see the categories icon, where you can go to discover items under Household, Electronics, and Apparel, etc. There's also a location tool to adjust your region.

How can you buy items?


When you find something you want to buy, be sure to tap on the image to see more details from the seller, such as a product description, the name and profile photo of the seller, and their general location. You can also save the item to find it later.

Once you decide you want it, send the seller a direct message from Marketplace to make an offer. Facebook does not facilitate the payment or delivery of items. The idea is you and the seller can work out the details.

How do you sell items?


To post an item for sale in Marketplace, take a photo of your item (or add it from your camera roll), then enter a product name, description, and price, and confirm your location and select a category.

You can then post it so that anyone looking in your area can find your item and message you if they want to buy it. Remember that Facebook does not facilitate the payment or delivery of items.

How can you keep track?

To keep track of all of your current and past transactions, visit the Your Items section from Marketplace's main screen. There, you can not only view your transactions but also saved items, products you’ve posted for sale, and all your messages with people.
