For the 3DS, users can save $1.50 when purchasing The Legend of Zelda or Zelda 2 - The Adventure of Link for $3.49 each. If you're not cut out for the NES era's "Nintendo Hard" mindset, the Game Boy Color's The Legend of Zelda: Link's Awakening DX is also available for $3.99, which is $2 cheaper than usual. For the Wii U, both The Legend of Zelda and Zelda 2 are available for $3.49.
Notably absent from this deal is The Legend of Zelda: Oracle of Seasons and its counterpart, The Legend of Zelda: Oracle of Ages, both of which are currently available on the 3DS eShop. It would also be nice to buy up The Legend of Zelda: A Link to the Past in preparation for the incoming sequel, The Legend of Zelda: A Link Between Worlds, but it has yet to reach the eShop on either console. Still, if you've yet to check out the series' origins, this seems like the time!
