I was 16 when I started reselling online. A few months later, my garage was a warehouse and I was making $25,000 a month. - Business Insider
This as-told-to essay is based on a conversation with Ethan Alexander. It has been edited for length and clarity. Each year, I get a $500 gift from an investment account that my great-grandfather set up for all of his great-grandkids. My gramps — Jack Davis — owned his own company and left a legacy of entrepreneurship in our family. I get the money on his birthday, May 9th. In 2025, my sophomore year of high school, I came across a video on Instagram about making a profit by reselling items online shortly after I received Gramp's gift. I had stopped playing lacrosse, my typical spring sport, and I was looking for something to fill my time. I used the $500 to pay someone to teach me how to resell. I didn't do much research, just thought "what's the worst that can happen? " The business took off immediately, and I generated just under $10,000 in revenue that first month. In August, I did more than $25,000 in revenue. I resold lots of goods at a relatively small profitSuccess reselling on Amazon comes from volume. I would find a product where I could make a relatively small profit margin — about $2 to $4 — and sell lots of it.
