How to make money thrifting
Research what thrift stores are in your area.
If you already enjoy thrifting, you'll know where to shop.
Spend some time on your local craiglist and other local selling websites to see what's selling.
You can also look on etsy, ebay, and amazon but your local sites will be the best indicator as to what prices are like. Decide what you'll be on the look out for and pick your specialty.
