From September 29 to October 5, Kmart stores in America will be offering an additional 50% off ALL clearance toys including LEGO. Many items however have not been marked down much so its about 50% off retail. Our members have been finding lots of LEGO items on sale so do check them out! Thanks to forum member trk for the heads up.
Forum member SlickP also reports to us from Florida that he found some of the newer sets at clearance prices as well (not marked, but scans at sale prices). For example, he reported finding 75019 AT-TE for $40.5 (reg.$89.99), 75016 Spider Droid for $11 or $14 (reg.$19.99), 2013 LEGO Star Wars Advent Calendars for $18 (reg.$39.99) and LEGO City Advent Calendar for $13 (reg.$29.99). Of course, these clearances could be YMMV.
