Facebook Marketplace is a great way to find and buy used items, but some people are having trouble posting items for sale. Here’s why: First, make sure you’re using the right Facebook account. You need to have a personal Facebook page to post items on Marketplace. If you don’t have a personal Facebook page, you can create one by going to www.facebook.com and signing in with your email address or phone number. Second, make sure your ad is set up correctly. You’ll need to fill out some information about your item and set a price. Make sure the ad is public so people can see it and click on it to learn more about it. Finally, make sure you’re posting in the right category. There are several different categories for things people sell on Marketplace: things people are looking for (like furniture or clothes), things people are giving away (like free stuff from their garage), and things that are for sale by businesses (like restaurants or pet stores). Find the category that best describes your item and post in that section! ..
