The LEGO Star Wars R3-M2 (40268) polybag is currently available for purchase at Toys R Us for $5.99 each. I’ve also been told that they have started showing up in stores but they do have a street date of August 26. Your mileage may vary at your particular store. I’m assuming there will be a promotion going on for them the week after. The item number for it is 814240.
Thanks to everyone who emailed in about it.
