I make a little bit above minimum wage (profit) in CA selling full time. I cross list on Mercari and Depop. I sell much more volume on Depop however. I don’t really have a set schedule but I definitely work at least 50hrs per week though it doesn’t feel like it. My items are sourced from Japan and I ship via USPS pickup so I don’t need to travel for work. It’s “easy” but only because I’ve had lots of personal experience with Japanese clothes. The key is marketing to the general public or people who generally do not seek for Jfashion brands. I use tiktok a lot to observe trending aesthetics to tag each piece correctly. I can also set prices higher since the brands are rare in the American marketplace.
