One of the greatest things about eBay is that it doesn't cost a lot of money to start selling stuff. In fact you don't necessarily have to spend a dime more than you already have! Just start going through your closets, toy boxes, kids clothes they no longer wear, etc... Research the item on eBay to make sure it is selling and at a price point you will be happy with. Then if the item is selling well list it.
The key to a successful listing of a used item is to start the auction price out low like at $0.99. Most anyone will bid on an item for so little if they are even mildly interested. The bid price will of course increase and many times you will sell a product for more by starting the price at $0.99 than if you tried to get $5 for the item. It is called escalation of commitment. Once someone has bid on your item they feel they have a certain amount of ownership for that item. Then someone steals their ownership away by bidding higher than they were willing to go. The war is on! Finally one of them wins the item because his opponent has no more money to bid. The winner takes all. The more bidding wars people have on your items the richer you become!
