Forum member elfabulosomicho reports that his Toys R Us store had the exclusive LEGO Ninjago 5002144 Dareth vs. Nindroid polybag (aka the LEGO Brown Ninja minifigure set). He said they rung up at $4.99 each. Not bad considering you get 2 minifigures (the Brown Ninja and Nindroid).
However, they’re not suppose to sell them as it was meant for a future event/giveaway. Hopefully, you’ll be able to find this set too as its just as popular as the 5002145 Galaxy LEGO Rocket Racoon Minifigure polybag!
