6. Shpock

Shpock – which is short for “Shop In Your Pocket” – is an app and website that lets you sell fee-free.

It’s quite similar to the aforementioned Facebook Marketplace, in the sense that it’s focused mainly on local selling – you post adverts for unwanted goods and buyers will generally come to your house and pay you cash-in-hand.

Be warned, there are a lot of hagglers on Shpock – and while there is an option to accept PayPal and post items, it’s not as popular as cash-in-hand (largely because Shpock doesn’t involve itself in any transactions, so you may feel more comfortable with those cash-in-hand transactions).
