Anthony,
Let me tell you how much is fair and how I arrived at this number. I believe $250 would be a fair price. The way I found this was I went to amazon.com and found each game in the condition I own it in, disregarded any shipping costs and took an additional 15% off the game.
For example if you follow this link
http://www.amazon.com/gp/offer-listi...1010076&sr=8-2
you will see The Legend of Zelda: A Link to The Past listed in very good condition at $17.94 (including shipping). Take off the shipping and you get $13.95 and take off an additional 15% and you get $10.46 which I rounded down to an even $10.00.
Because I can tell you're eager to have these games I could probably meet with you before the weekend is here.
