There are a lot of Lego sales going on this week. Target, Toys'R'Us, Kmart, and Lego all have some sort of sale or promotion running.
The Lego one features several Legend of Chima sets and Double VIP points.
The Toy'R'Us sale is a BOGO50% and 30% off select sets.
The Target promotion is a 20% markdown of the Galaxy Squad sets. (I'm only showing one because I don't have a generic link.)
Kmart has a 15% off on all TMNT, Chima, and City sets.
Good luck shopping!
