For the 4th of July weekend, Toys R Us is offering a sale on "All Star Wars and Hero Factory." Now, most of the deals are essentially null considering the "TRU tax" mark-up. However, there are a couple of actual discounts.
>>7879 Hoth Echo Base- was $89.99, now $66.49 (about 25% off)
>>10188 Death Star- was $399.99, now $359.99 (about 10% off)
>>10212 Imperial Shuttle-was $259.99, now $233.99 (about 10% off)
They're also giving away a free 30086 Ninjago Hidden Sword ($4.99 value) "with ANY LEGO construction set purchase of $20 or more!" It looks like you might have to add it manually when shopping online. Watch out for that.
Sales are valid through July 2nd. Yeah, that's right. TRU's 4th of July sale ends on July 2nd.
