I wouldn't pc it down yet, though I think some used to go back and forth more frequently than a year but with how things are changing I don't know that I'd do that. If you still have a support link for the CSP it should still work. Mine still does though I think I'm still waiting for the last support to post.
The other option would be have him apply for the CSR then he'd get another $300 in credit. Especially if he's doing most of the grocery shopping, I think that you can redeem URs for them past the end of this month. But I think the extra points for grocery shopping finish on the 30th right? I should really pay more attention but I've been working on an msr so I haven't been using it as much but have made a few grocery purchases on my csr and cf for the extra points. I just know my hilton is through the end of July so I'll finish the last $250 of it at safeway for the 12x points.
I know the CIP support is basically dead and that I shouldn't count on those ever appearing, but have the CSP support started taking longer than it used to? Probably more of an
@Albort or
@SouthFayetteFan once he's back home question. I haven't seen anything on r/churning about them but I also haven't been looking.
