I’ve been told that The LEGO Batman Movie The Joker Battle Training (30523) polybag has been found at Walmart on the east coast. There’s no other details that was given but I assume they were found in the LEGO section for $3.97 each. I’ve never seen any polybags at my stores except during the holiday season so they may not be at every Walmart. If you’ve been looking for The Joker Battle Training, you might want to check yours out to see if they have it. I’ve already done a review on the polybag which you can read it here.
Thanks to Fikinbricks for the heads up.
