Ok, I know the title is a little deceiving, but I am curious as to why the prices of Refined Isotopse on the GTN have jumped up to almost 1 mil a piece. Did I miss something that has occured recently?

Somebody probably bought all of the listed refined isotopes and re-listed them to turn a larger profit margin. It's not a nice move, but profitable. It happened to the augment mk-10 kits a while back too.

It definitely sounds like someone bought up all the listed isotopes and relisted them for a higher prices.

 

1,000,000 per item is definitely not the norm. 200,000 to 250,000 or so seems to be about the average now.
