Walmart offers the LEGO City Pickup Tow Truck, model no. 60081, for $15.99. (Kmart and Amazon charge the same.) Opt for in-store pickup to dodge the $4.97 shipping fee. That's tied with last week's mention and the lowest price we could find by $4. This 209-piece set includes two minifigures.
Toys"R"Us takes 20% off select LEGO Star Wars sets, with prices starting from $3.19. Plus, take $5 off orders of $25 or more via coupon code "970299". Shipping adds $5.99, but orders of $49 or more qualify for free shipping. (In-store pickup may also be available.) Some exclusions apply.
Fry's Electronics offers the LEGO Guardians of the Galaxy Milano Spaceship Rescue, model no. 76021, for $59.99with free shipping. That's the lowest total price we could find by $7, although we saw it for a buck less during Black Friday week for new customers. This set includes a Milano Spacecraft, Necrocraft, and five minifigures.
Update: It's now available for in-store pickup only.
