You got yourself a great deal from the sounds of it.
So I have been running the numbers through my head and I think I "may" have figured this out. Possibly. So a buddy of mine works in a game store in Virginia. he told me that usually stores will either offer one of two deals for trade ins: credit value or half cash value (ie 20 credit or 10 cash) or credit value and 2/3 cash (ie 20 credit or 13 cash). It depends on the store.
If this lady was new, and when I said I wasn't sure if I wanted cash or credit, she may have found the cash value and doubled it, as opposed to finding the 2/3 factor. That might explain it. $125 cash or $185 credit seems a bit more plausible.
Anyway, I have more doubles and extra systems laying around. I might find out when she is working and go back. I could use a new Neo Geo
