Well this is a debatable issue. Tonight before gaile gray announced that IDS will continue to drop after Wintersday the average price was between 50-65k.
After this announcement people are offering 1k, 5k and 20k while sellers are maintaing 50 k prices or just being stubborn and asking for 80-100k (doubt they will ever get that).
As it is supposedly going to be a rare drop it's hard to say where the price will end up but most likely less than 50k...so I would advise to sell now for as high as you can and not in the Granite Citadel.
Thanks, the past couple of runs (5-6 of them), there have been no IDS drops. Not saying they are now EXTREMELY hard to get but they have gotten harder to get since yesterday. Thanks and I have aso found a comfortable price range of 35k-70k.
