Walmart offers the LEGO City Space Port Space Starter Set, model no. 60077, for $6.39. (Amazon has it for Prime members for the same price with a $25 purchase.) Opt for in-store pickup to dodge a $4.97 shipping fee. That's $2 under our February mention and the lowest price we've seen. (It's a current best by a buck.) This 107-piece set includes four mini-figures with assorted accessories.
