As a Seller, you will first need to acquire the Winner's address first and then either visit your own local post office or look it up online. Shipping costs very depending on the distance between the users, the size and weight of the item.
The safest way is a money order, you have a receipt and as soon as I get it I will send the item to you, I suggest that if you plan on using this site or any that you have to pay, you set up some kind of cash transfer to be safe.
