Barnes & Noble takes 50% off a selection of LEGO building sets. (Prices are as marked.) Shipping adds $4.99, but orders of $25 or more receive free shipping. (In-store pickup may also be available, and some items are in-store pickup only.) This elicits a series of impressive price lows. A couple of best bets: LEGO DC Super Hero Girls Lashina Tank for $7.47 (low by $7) LEGO The Batman Movie Killer Croc Tail-Gator for $34.97 (pictured, low by $23)
