"Over one million items pass through the store annually. About 60% of the merchandise is clothing with the balance of the store dedicated to cameras, electronics, sporting goods, jewelry, designer optical, books and of course, luggage. The vast majority of items are from unclaimed baggage which, after at least 90 days of intensive tracking by the airlines, are declared unclaimed. However, lost and unclaimed cargo is also now available in special areas of the store."
