To be a good reseller, you’ll need to do your research to understand what will sell well in whichever venue, platform, or marketplace you’re using. Rather than sell anything you can get your hands on, choose a niche or sell items that reflect a certain aesthetic or lifestyle. If you’re selling online, make sure you take clear pictures of your items, write detailed descriptions, and respond to customer questions and feedback in a timely manner. Package your item neatly, ship it promptly, and include a personal thank you note. All of these actions can go a long way in increasing your following, your review stats, and the number of sales you make. With these tips and a little bit of effort, I was able to garner more than 475,000 followers on Poshmark and become a top seller.
