I have found that although smaller sizes in gymboree clothing are not a huge seller on Ebay, what I have discovered that if you purchase these items (small sizes) at a great cost and place a hot selling item with it as a complete set it will sell more rapidly than listing the items as individuals. For example, if you have a less desirable top from a certain line and you place a hair clip and socks that are highly sought after them you are apt to sell the top more than listing it by itself. Research what sells and what are the most highly sought after items. Girls size seven is a  popular size that sells on Ebay. So do your research before you begin your store.
