The Modular Modern Home (31068) is only $24 which is a very good price for this particular set.
The Modular Poolside Holiday (31067) is down to $23.99 from $29.99.
One of the my favorite smaller sets is the Robo Explorer (31062) which is now at $15.99. I absolutely love the color scheme on this set.
Another set that I really like from this group is the Space Shuttle Explorer (31066) which is now at $23.99. I might have to pick up another one or two of this one to display them in their alternate builds.
Finally, we have the smallest set of this group which is the >Mighty Dinosaurs (31058) which is going for only $11.99.
