Eh, I've flipped CAG things before. Who knows what his situation was. It could have been exactly the type of situation I have had on occasion.
I have the money, want the game and, by the time it gets here... There is yet another family emergency requiring me to unload what I just got without having even played it!
Seemed like that happened to me every couple of months for about two years, hence the never ending streak of lowballs I held a couple years back.
Personally, if OP was happy with his 8x flip, then I'm not sure I would begrudge the next guy his 3x flip.
