As all of you know, SMB/Duck Hunt is one of the most common game carts out there (if not the most! ) That being said, it's obviously extremely easy to find one on the cheap - in fact, I've heard stories about the big chains GIVING AWAY SMB/DH carts at one point!
But every now and then, and it's happened to all of us - we'll run across an overly expensive one. Maybe it will have a price tag with four digits, and you'll have to keep yourself from laughing as you think "they're NEVER going to sell this."
So tell us, what's the highest price you've seen for an SMB/DH cart in the wild?
Personally, my experience isn't too exciting - I've seen one or two priced at $10 on separate occasions, and that's about it.
