Ocarina of Time you mean? You didn't mention if you are looking for it for the 3ds or Wii U or Wii. The games are not cheaper in the Eshop, they are the same price. I know the details for the Wii because I have the digital version, but for the 3ds I have the physical copy. For the Wii it costs $10, and takes up about 38 megabytes of space, or as Nintendo says it, 300 blocks. For the 3ds, it is still $40, because it is the remade 3d version.
