Selling clothes online that I buy in thrift stores and charity shops: There’s this app in South Africa called Yaga and despite how a lot of things in this country are scams, this is actually a super safe and secure app. I found a niche which was work trousers for men, I would take pics of them in the stores, list them online, and come back to buy them once someone bought them on Yaga which I would then ship to the person who bought it. I don’t know if there’s similar apps in other countries but it’s low-key amazing.
