You'll be able to get Super Mario Bros. (NES) for $4 from July 26 to August 1. Starting August 2, Super Mario Land (Game Boy) will be $3. Super Mario Land 2: 6 Golden Coins (Game Boy) will be on sale for $3 on August 9. Mario's Picross (Game Boy as well) will be $3 the next week, starting August 16. That's a dollar off the normal price of each.
That's also a lot of Mario games to play before ... another Mario game!
