You can't leave negative feedback for purchasing an item that you willingly paid even though you knew it was overpriced in the beginning. That's not how it (ebay) works. I wouldn't be surprised if the seller would contest that.
I was only joking.  I wouldn't really do that.
tpivette:  That's kind of how I was looking at it.  A couple are dupes and a couple were already open (sidearms, galaga, alien crush, last alert).  Sidearms had a price sticker on it from Babbages for 99 cents.  Wish THAT deal was still happening.  It reminds me of my experience when I bought Exile 2 brand new at toys r us during turbo clearance sales.  The woman at the counter gave me two of them (they were stuck together) and I didn't notice until I got home (figured it was a double jewel case or something).  Well, low and behold, they separated.  And being the jerk kid that I was, I promptly returned one and got my $10 back.  Yeah me, smart move.
