When thinking about where is best to sell things, it is important to consider what you want your final goal to be. Do you want to make money, build a relationship with customers or simply have an easier time finding a buyer? In order to decide where is the best place for you, think about your goals and how selling can help you achieve them.
A few places that are great for selling things are garage sales and flea markets. Both of these events offer the opportunity to connect with potential buyers face-to-face and make some extra cash while doing so. Additionally, both events have a wide range of items available, so there is likely something that will fit your needs.
If selling online is more convenient for you, then selling on websites like eBay or Etsy may be a good option.
