It can take up a week for delivery, if you're angry about the charity donation.  I've seen a couple of off-comments about it, skimming.  The system has been reliable.  Hold on, and it'll arrive.
But on the present topic at hand:  I was not apart of the Beta, so I cannot speak to what changed from pre-launch to today as pertains to the monthly credits for the premium shops.  However, $35 in the hole (purchased before July, for full transparency), I cannot say that I'm disappointed.  I appreciate the clarification around my premium badge, and I see great potential for this site.  This is week, what, two?  Right?  (Two, I think, correct me if I've lost track of real time).  I'm really looking forward to spending the rest of 2020 here.
