If you live near a walmart, now is the time to grab any Kingdoms sets. One of my local wms had all Kingdoms (and some Ninjago, Toystory, Cars2, StarWars, City, Atlantis, Pharoahs) sets at 50% off on 12/26.
Mill Village Raid $34.90
King's Carriage $19.90 (SOOOO GLAD I waited on this one!!!)
I was at a different WM yesterday and found
Escape from the Dragon's Dungeon for $9.90
Also,TJMaxx and Marshalls, two closeout stores here in the states had Atlantis, Prince of Persia, and even a few Kingdoms sets before xmas. They should be marking any leftovers down now, but I haven't checked them.
