A lot of the CE have dropped in prices.
Uncharted 3 CE at BB is only 30 dollars.
Skyrim CE at GS is 60 dollars.
FF13-2 is 40 dollars at most stores.
SoulCalibur V CE 40 dollars at GS.
Mass Effect 3 N7 CE 30 dollars at GS.
And so on. I recomend if you want a CE you look at the stores prices right now because it probably cost less if it has been out for more then 6 months. Some might be sold out by now though.
not many collectors or limited editions are worth the asking price, if a game is made by a big publisher chances are there will be plenty meaning 4-6 months wait time but can pay less than half the price
i wanted witcher 2 dark edition i think it was called and around me in new orleans total of 8 gamestops got 1 and that was a pre order. so sometimes its hard to judge, i just got max payne 3 for $30 when i pre ordered GTA5 which i was planning to buy anyway. so that's huge saving for a game that came out not that long ago
these 3 are the ones i see being very limited
