Walmart offers the LEGO Architecture New York City, model no. 21028, for $45.83. (Amazon charges the same.) Opt for in-store pickup to dodge the $4.97 shipping charge. (Alternatively, pad you order over $50 to bag free shipping.) That's tied with yesterday's expired mention as the lowest price we've seen. (It's also a current low by $2.) This 598-piece set measures 10" x 9" x 1" when fully constructed and features the Flatiron Building, Chrysler Building, Empire State Building, One World Trade Center, and Statue of Liberty.
