Obtain a collectible coin when pre-ordering Super Mario Odyssey in-store or online at Best Buy in the US. The flyer was provided to people who attended the Nintendo World Championships at the Bronx Terminal Market, courtesy of VGTidBits.
The ad also mentions that My Best Buy Members can get $10 in rewards when you pre-order the game as well. The coin will be limited in quantities and requires a $5 deposit when you pre-order your copy in-store and full payment when pre-ordering online.
