17. eBay

We’re now going to list some very specific platforms on which you can sell your old clothes, starting with a very obvious one; eBay.

eBay has almost 200 million users and its mass audience is its main selling point – so it’s a great place to sell old clothes, as there’s bound to be someone out there who’s interested in what you’ve got to offer.

It’s extremely easy to use – and while its mainly known for its auctions, eBay also allows you sell for a fixed price (with a useful option to receive/accept best offers).
