I've already gotten some cool free stuff and I haven't spent a penny. I also sold something today and I paid for the shipping (a stamp). You don't always have to pay for your own shipping while other times you do. It just depends on the lot you bid on and how you set up your own auctions.
It's a lot of fun and I'm finding it quite addicting. I loooove freebies, and at the same time I can put to use things that I no longer use or need. Try it out! It's really awesome!!
They have video game consoles, arts and crafts stuff, jewelry, trading cards, and pretty much everything imaginable. You never know what you'll find! I'm currently following some awesome pendants, beads, seeds, boots, and other things I'm itching to get. You know what they say, "One person's trash is another person's treasure."
