Except has there ever been a (specfically) Best Western offer in the past? That's the offer which some people got a $20 off version while others got a 2000 MR points version.

I've not seen any hotel offers for MR points in my account lately, but until now I've not seen anyone else posting about seeing them either. So for other hotel programs, yes, I used some $$-off versions because that was all there were before AFAIK.

I did an use extra (flat) MR points offer for Whole Foods about half a year ago, and I recently I got a 1 extra MR point per $ (ongoing) for Whole Foods in several MR cards (I activated it for Everyday since that's what I use for groceries).
