Shopping online is simple, quick and a playground for scammers.
But some popular sites can make you an easier target than others.
Here's how to avoid falling victim.
Gumtree tips to stay safe online:
1. When buying or selling, you should always meet in-person to see the item and exchange money. If possible, take a friend or family member with you, or make sure there is someone else at your home or workplace.
2. Never send money to anyone you don't know. Gumtree does not allow users to transfer money via the website, and advocates face-to-face transactions.
3. Always use common sense - if it looks too good to be true it probably is!
