Grannygirl, the items in the World Market are offered to a large number of players at the same time. Very often, especially with a valuable item, many people have seen the item at about the same time as you did, but they were just a fraction of a second faster when pressing the button to buy it. It's a race, so you have to be quick -- and hope that you are the quickest. If not, then wait and look and try again. Good luck!
