You can make extra money left and right if you just know where to look. If you like to ‘tinker’ I’d suggest going to the DIY section on Pinterest. You can find thousands of projects there to make, and you can sell them at a nice profit. You can make 20, 30, or 50 bucks at a time, in real money. Not the ‘get rich online now!’ stuff you see around. I make old teapots into lamps, or old shirts into aprons and sell them locally on Kijiji or Craigslist. It’s totally doable.
Hunt for under-priced used books that you can sell online. Download an app that reads ISBN numbers so you can scan the barcodes on books. This will pull up the book’s current price on Amazon so you can see if it’s worth trying to resell it. Then, visit used book stores, thrift stores, and garage sales to look for high value books. Post the books for sale online using sites like Amazon or Ebay.
