If you have an Xbox 360 i believe you can buy it in the Xbox Live Arcade thing that lets you buy games. If its not on sale it's $15, or 1200 Microsoft Points, but if its on sale it just $10, or 600 Microsoft points. If you don't have an Xbox 360 and you want to get it for the computer, check Amazon.com or EAgames.com, and look up Portal in the store.
You can buy Portal through a program called steam. store.steampowered.com
yes there is a smaller portal of power for the 3ds game Skylanders you have too buy the game and it will come with a mini portal. P.S. don't forget too buy some Skylanders! :)
