November 25 Update: Modulars and other online exclusive sets are excluded again (despite the fact that the ad did not mention any of these exclusions).
This week from November 25 to December 1, Toys R Us America will be offering Buy 1 Get 1 50% off ALL LEGO. The ad mentions that it excludes books, Galaxy Squad, Ninjago, Video Games and Video Games accessories. Thanks to forum member legobricks for the news.
Tip: Remember to purchase your $10 Groupon for $20 Worth of Toys at Toys R Us! Hopefully, this will help you pay off some of their markups.
