From a $60 game to $37 dollars in a couple of weeks, there's an upside to having a checkout box next to the banner ads and infomercial like reviews, they show you just how much money you can save by waiting.
Curiouser and Curiouser GameSpot. That response was rapid fire.
It should never have went down to $37 it seems. Odd that you saw it listed as that at one point. Right now the PC version is unavailable in hard copy (limited edition, the only edition anyways lol) and only available as a download code for $49 on Amazon.
I preordered mine from Walmart for $49, being that I had a gift card, & it still is $49 from Wally World. Glad to see I didn't miss the sale of $37 on Amazon which never should have happened anyways it seems.
EDIT: Well it also seems that price of $37 was for the 360 version which probably means it was the lowest used price hahah. My mistake I thought this was a PC only Metro forum I guess it is for all versions though. But that explains the price you saw. We all have lapses of judgement and I totally understand your excitement at seeing $37 and thinking there was a price drop on the retail copy, unfortunately Amazon lists prices funny and sometimes will show the used price on that tab in the pic u posted.
