If you’ve been selling on Poshmark, Mercari, or Depop for more than five minutes, you’ve probably run into a sketchy message or two. From fake buyers to refund tricks, there are definitely some red flags/scams to watch for. Here are a few common ones to keep on your radar so you don’t get burned.

If you're like most resellers in the U.S., you probably think of Mercari as that easy, mobile-friendly marketplace where you can quickly flip everyday fashion, beauty, or home items. But here’s the tea: Mercari actually started in Japan back in 2013, and while the U.S. app has grown steadily since launching here in 2014, the Japanese version is still thriving — and often serves as the testing ground for new features and policies.

If you’ve ever found yourself frustrated by lowball offers or exhausted from constant offer management, you’re not alone — and it looks like Poshmark is finally paying attention. Some sellers recently spotted a brand-new feature called Smart Sell, and while it hasn’t been officially rolled out to everyone yet, the potential is exciting.

So what exactly is Smart Sell, and how does it work?

Big news for resellers on Mercari: Starting July 2025, Mercari is piloting a Fashion Exchange program that could significantly impact how buyers shop—and how sellers list.

This limited-time pilot offers buyers a 72-hour try-on period for select fashion items, giving them the option to exchange purchases that don’t fit, don’t meet expectations, or even don’t smell right. Here's the best part: sellers still get paid.

Let’s break down how it works—and how you can use this to your advantage as a reseller.
