Welcome to the world of exclusives. Were they the Panasonic 3D glasses? Panasonic used to sell some glasses with Avatar packed-in. What you saw was left over stock from that promotion most likely. Hold off, the Panasonic exclusivity window is ending (you can no longer get Avatar by mail rebate for buying a Panny BD player or TV). Avatar will probably have a general 3D release this fall unless it becomes a retailer exclusive for Best Buy or another major B&M store.
