The Nintendo 3DS is in its twilight years. Even though few new games are coming out for the handheld, the catalog of quality games to play is quite large.
Among them is Super Mario 3D Land. The game is part of the Nintendo Selects program, which offers top-selling older games at a discounted price.
Right now you can save even more on Super Mario 3D Land. Amazon has the game on sale for $15.94 with free Prime shipping. If you don’t mind playing a used copy, you can get it for under $10 on eBay.
