Just been doing a forum search to work out the timing of this myself.
Last year I used both vouchers, and just like status I assumed that as I am currently PC+ I would be entitled to two more vouchers this year (my birthday is this month) yet nothing has shown up. I did have a hotel voucher previously showing in the usual spot, and did use it so it no longer shows, but no wine vouchers yet. I also have the correct emails turned on.
I'm well on my way to re-qualifying PC+, but have so far only got to 300k points, so at the very least I would expect a single $50 voucher if they're going to be stingy.
Has anyone with a September birthday received their vouchers yet and/or recent experiences from say, an August or July birthday on the timing of receiving the vouchers?
