I purchased this online for around 11,000 yen. I only wanted the Mario and Luigi RC cars, but I accidentally bought the set with the course... This is a listing for the unopened, unused course only. Please make sure you understand this. To buy the course, it seems you need to purchase the full Mario & Luigi set, which retails for 11,000 yen. I hope those who want to expand their course will consider purchasing this.
