listia is just like ebay but instead of cash, you use credits to bid (some items charge for shipping, so you have to use cash for that) but items with free shipping you use zero cash, by the time the clock is zero, and you are the highest bidder, you won that item and you send the seller your shipping address(mostly listia seller only shipped to verified adress, for security) make sure to verify your address, and the item will be sent to you,
