Windwaker and Sunshine can be had for $15 each if you have a Best Buy that has the gamers gift card ($5 off any game $19.99 or up). Might be the cheapest price on them
Also for the sounds of your first post, you were looking to buy them from someone on this site(from the paypal payment method). If that's right, this should be in the Cheap Ass Trading section of the site.
