In hopes of making a little money back, I send them good quality, never worn items, even with price tags. They show you how much they sell it for the profit ends up being less than 5% of the sale. They have a service fee of $14.99 that gets deducted from your earnings.
The only way to get payout is through paypal. Do not use them if your purpose it to make money. They are only good for donations. I wish I knew this before I sent them my good quality items. You are better off selling your stuff privately.
