If you haven’t tried Lister yet, I highly recommend it. I set up two shops earlier this year and they weren’t really selling many posters, maybe one a week. Since using Lister I’m listing 100s of posters every week, it’s saving me hours, and now the sales are coming in every day. Well worth it, although I’m probably going to have to start declaring my income for tax soon! Not a bad problem to have, I guess. 😅
