I just received two mailers from Harrah's Rincon with offers for March and these offers were deeply cut:

My U Choose offers for Monday, Tuesday and Wednesday are now for $90 each day (up from $80 previously) BUT in order to claim the $90 of reward credits or dining credits or free play I first have to put on 50 tier points. To get 50 tier points I'd have to have coin-in of $500 of video poker. In previous months, I'd just have to swipe my card to get the U Choose offer with no previous play required.

My offers for each Friday in March, fee play or reward credits, were reduced by about 1/3 from previous months.
