Experiences selling on Depop?

Hi All,

I've been reselling on eBay, Mercari & Etsy for a few years now & opened up a Depop store a few months ago, just cross listing the clothes, accessories & pop culture stuff I have for sale. I've made a few sales, but mostly it is just "Likes" and people sending me offers that once I accept they never pay. Is this pretty much what Depop is? Does anyone have a lucrative Depop business, or is it basically just like Pinterest or something? If it is then I'm not sure it's worth the time I'm putting into it. Thanks!
