PokerStars has reduced many/most of their Guaranteed Tournaments
I dont have a complete list--but many of the daily Guaranteed Tournaments that Stars runs daily have had their Guaranted Prize Pools reduced in the last couple days.
I just happened to notice the $2.75 $10K reduced to $7500, as well as the 3 5 and 10 rebuys with pretty dramatic reductions. Hopefully, they will move back up after the WSOP
and/or these processor problems are hashed out.
10 70k-50k (down from 80k)
11pm 109 40k-25k
Super Tuesday 300k-250k (at one time was 400K)
