I found a (deal is now DEAD) Best deal is the
50, 000 point link (50k deal dead now too) now (also NOT my link btw) working 60,000 Point CitiBank Thank You card link (note this is NOT my link)! It is clearly better than the 25,000 one I can offer. This one seems only to be valid until June 14th but these kinds of offers can disappear quickly as we all know. You do have to spend $4000 to get all the points but if you are thinking about a round, this would be a good one to look at.
Maybe to round out your round you could look at:
A nice 130,000 point round after spending $7500. Oh how I long for the days when we could get this many points for spending just ONE dollar! – René
