If enough buyers open 'item not received' cases, and leave negative feedback, Ebay will eventually take action.
Check the email you received when you paid, and, if the item you bought doesn't arrive, open a case as soon as you can.
"There are two ways to be fooled. One is to believe what isn't true; the other is to refuse to believe what is true.”
Søren Kierkegaard, Danish philosopher (1813 - 1855)
