Toys"R"Us via eBay takes up to 35% off a selection of LEGO sets. Choose in-store pickup where available to dodge shipping fees, which start around $5. (Otherwise, orders of $49 or more bag free shipping.) A couple of best bets, via in-store pickup:

• LEGO Duplo Disney Planes: Fire and Rescue for $20.78 (low by $3)
• LEGO Teenage Mutant Ninja Turtles Mutation Chamber Unleashed for $22.99 (pictured, low by $6)
