Not sure how long this is going to last, but right now LEGO sets are BOGO50 – buy one, get one for half price at ToysRUs.com. This covers almost every set, including those in Star Wars, Lord of the Rings, the Hobbit, Marvel, DC, Lone Ranger, Teenage Mutant Ninja Turtles, and more – even their girlie Lego Friends sets if pastels are your thing.
There’s a handful of sets that are already deeply discounted so those won’t count, but there’s still big sets like the Millennium Falcon and Jabba’s Palace that you could combine for some pretty big savings. I’m not sure if these qualify for the free shipping for purchases over $79 deal, but if they do, that wouldn’t be that hard to do with LEGO. 😀 Happy shopping!
