The rare Kreo Stinger Replicator Chamber is back in stock - US$40 (VERY expensive because it is similar size/pieces to Dinobot Charge, which is only US$10-12)

Also back in stock as a pre-order is the next wave of convertible Rescue Bots (new Optimus, new Boulder, new Chase, and Salvage the dumptruck) - US$40
If you collect Rescue Bots, or buy them for your youngster, secure them while you can, as the secondary prices are insane for the ones that sell out or have limited release (like Salvage will).
