Barnes&Noble.com has a one-day Buy One Get One 50% off sale on all LEGO. Free shipping kicks in if your order total is $25 or more. Be aware that some items are offered through their marketplace and will thus be priced higher and will not be eligible discount. Obviously the deal works best when you can buy two items of the same price to maximize the discount. After spending a few minutes searching, their selection for licensed sets is pretty slim. The only big ticket item I was able to find was Lord of the Rings 9474 The Battle of Helm’s Deep for MSRP. Getting two of them totals out to $194.92, or just $97.46 each before any tax and you’ll score free shipping. And I believe that members will also save an additional 10% off on top of that.
