Consignment stores are not just for buying things, you can sell stuff there too.
If you have a horde of gently worn clothes and don't want to just throw them out, sell them to a consignment store.
Recently, my son brought his old football spikes and baseball cards to our local consignment store. It didn't take long for them to be sold, and he earned around $30 for the entire set of cards and spikes.
For those who don't feel like selling on eBay or Craigslist, give a consignment store a try.
