How Much Money Does A Nintendo Wii Memory Card Cost?

My mom and Dad recently bought a Nintendo Wii and my sisters, father and I have been playing with it non-stop ever since. The only problem is that you can’t save your Nintendo progress without a memory card. And you can’t make a ‘mii’ character without it! (Included Avatar activity) So if anybody knows that average price for a Wii Memory card, I would appreciate your answer so that I know just how much I need to save up. Thanks!

How Much Is A Nintendo Wii And Guitar Hero 3 Together?

I’m buying these two products for myself for the holidays and am wondering how much they are at Best Buy. I know that the nintendo wii is $249.00, but I couldn’t tell how much guitar hero 3 is. (for the wii) Also, do I need to buy anything else besides the wii [and the game-guitar hero 3]? I’m asking if I need to buy the controller/guitar(s) separately or do they come with the wii/game?
Thanks!
