Walmart offers the LEGO Creator Airshow Aces Set for $13.49. (Toys"R"Us charges the same.) Choose in-store pickup to dodge the $5.99 shipping fee. That's $3 under last week's mention and the lowest price we could find by $3. (It's also a great deal at about 5 cents per piece, when the average is around 10 cents.) This 246-piece set featues a supersonic jet, classic propeller plane, and transport truck; it also includes instructions for two additional designs.
