The current eBay listings are asking $150 and $200 for the game. Too many people who don't understand the difference between asking and sold prices will look at that and think that $80 is half price or better, when by eBay standards it's actually four times the going rate.
The problem is that every time someone gets duped into grossly over paying, it drives up asking prices even further. So although legit prices will continue, it thins them out by clogging up the internet with a bunch of rotting overpriced listings. Unfortunately, investment flippers would rather sit on a game for 5 - 10+ years, waiting for an unsuspecting insta-set-collector to make an impulse buy, than break even or worse. Selling a game for even a dollar less than they paid years ago defeats the whole point of gaming to these people. See the unsold Bonk 3 manual on eBay.
Since his link was showing $150+ i guess i missed that.
I don't know if your cookies or mine are affecting the link, but click on "Sold Listings".
