Ebay is where you'll find a bunch of overstock starting at around 50% off. This includes Warmachine/Hordes, AT-43, Confrontation, and a few nifty items, like the Blood Bowl box set. If you win on eBay, you can pick up the items at the store and avoid shipping. Keep checking back, as there will be a lot more in the coming week.
