Although I bid very rarely, I occasionally browse shopgoodwill.com to look at the cool stuff that is donated to the various Goodwill organizations around the country. Today, I found this:
http://www.shopgoodwill.com/auctions/Lot-of-9--Nintendo-Games-15493886.html
which, although it was only listed today, has already received 10 bids and an auction price above $500. It will be interesting to see the final sales price. (When you reach those sort of numbers, shopgoodwill.com's exorbitant shipping costs don't matter too much...but the fact the items are untested does...)
EDIT: The last one available on eBay sold with a "buy it now" price of $1000. The copy of Silent Service included in this lot will probably push the price much higher, however...
Mod edit - I trimmed this out so it doesn't contaminate the happy go lucky LOL finger pointing of the original thread - Hobie
