Do you enjoy hunting for bargains that you can buy low and sell high? Charlie William does, and his book flipping business is proof that this business model still works. He’s become a master deal-hunter, selling more than $9,000 worth of used books last month on Amazon.  The best part? Anyone with access to thrift stores, yard sales, and local charity shops can get started with this side hustle for just a few bucks a month. I connected with Charlie though the Side Hustle Nation Facebook Group and invited him on the show to learn more about the book flipping business. Tune in to hear: How Charlie got started flipping books. The tools and software he uses to run his business. Where he sources profitable inventory. What it takes to make this side hustle profitable and successful.
