Kind of a late notice considering it's Thursday and the sale started on Sunday, but I got an email today saying that Target.com brick'n'mortar stores as well is having a LEGO BOGO 50% sale. Discount applies to all LEGO Creator, LEGO Games, and Ninjago sets but excludes the CCP Spinner packs. Some sets qualify for free shipping
Of course, the only thing better than a BOGO 50% off is just 50% off. Target also lists LEGO Space Police III 5982 Smash'n'Grab for the low, low price of $9.98, that's 50% off MSRP. They also have LEGO Atlantis 8059 Seabed Scavenger for half off, $7.48.
