Yard sales are a great way to find amazing goods at rock bottom prices. Unlike most thrift stores, people who price yard sale items rarely have any idea about the resale value of things. Not only that, they are usually open to negotiation! Use an app such as Yard Sale Treasure Map to find yard sales close by you!
Also, don't underestimate the power of a yard sale for unloading your own items. Since we don't own a brick-and-mortar shop, we typically save heavy or low value items and have a yard sale once a year to unload dead inventory and deathpile things we no longer want to list.
