I think I wrote about 21018 United Nations Headquarters recently, but it is on sale again. The set is a good mix of pieces, and when on sale, it is a good deal.
Target has it for $40.99 or $38.94 each with RedCard discount, limit 8.
Walmart has it for $40.48, limit 5.
And Amazon has it for $40.48, limit 2.
The Part out value is $99.92 or 2.52x when averaged at $39.66 each.
