Course Overview

What this course is designed to develop

Most people who try reselling lose money because they buy things that look valuable, guess at the price, and forget the fees and shipping that quietly eat the margin. This course replaces guessing with a system: you learn how resale profit is really calculated after fees and shipping, how to read sold comps in the eBay app and on Google Lens before you ever pay, which categories beginners win in, and how to photograph, price, list, and ship an item so it actually sells. You finish able to walk a thrift store with a sourcing checklist, scan an item and know its true resale value in seconds, list it well across eBay, Poshmark, Mercari, or Facebook Marketplace, and track cost, fees, and profit per item so you know whether your hustle is working.
