Two new New Super Mario Bros. 2 Coin Rush levels became available for purchase shortly after the Nintendo Direct presentation this week: "Gold Mushroom Pack" "Coin Challenge Pack B."  Each is available for $2.50 (or as a set for $5), and "Coin Challenge Pack B" also supports a high score table on the NSMB2 web site.  Visit the shop section of Coin Rush mode to purchase these levels.
