Each year Toys ‘R’ Us does a “Bricktober” special set of minifigures. Mostly they’re not too exciting, but this year’s set appears to be a set of 4 unique LEGO Batman Movie Minifigures! PromoBricks.de broke the news first today.
Information is scarce right now beyond the images, but they will likely be free with a purchase of a certain amount ($75 or more?). In years past, excess sets were sold separately after the October period, but I doubt these will have any left overs.
According to TRU in Germany, more details will be announced on Monday (Thanks to Google Translate for the English version):
ToysRUs Germany has registered with us through our Facebook page : Dear friends , there is no need to worry! From Monday you will learn everything about the action. The article in our onlineshop was probably a small prank of the technique. As technology does not seem to be as expected as her. & Think, anticipation is the most beautiful joy. Best wishes, your Toys “R” Us Facebook Team
