so if this is a repeat forgive me….But my thought is you need to know when to sell what. And where. At garage sales people want bargains. They aren’t going to pay much for just about anything. Online places like ebay and craigslist are always going to be hit and miss.
I don’t know if you belong to facebook, but there are some groups forming (like google) there, You can search for online garage sales or swap n shop groups in your area. I live in a small town and there are about three for my county….which is bigger but most of the other towns aren’t far away. They have rules so make sure you read carefully before selling. I sold a $20 gift card for $15.
