Are there any consignment shops near you? There is a small shop in our small town, and it's great. I bring in our lightly used clothing and the shop in turn sells them and splits the profits with me. The first time I did this, I dropped off two bags of clothing and checked back a few weeks later to find that I had made $70. Woohoo! Not a bad piece of change for some quick de-cluttering. I've heard that these types of stores in urban areas can bring in much more.
How about you? Have you ever had any luck with consignment shops?
