At Amazon, buy one select LEGO or Nerf toy and get 40% off a second select toy. (Discount is applied at final checkout.) Plus, Prime members bag free shipping. (Non-members can spend $35 or more to qualify for free shipping; otherwise shipping starts at $3.99.) That's one of the strongest toy sales we've seen from Amazon this year, with many toy pairs at significant price lows. A couple of best bets, before discount: Note: Discount only applies to items sold by and not by a third-party seller.
