Hey there!
I've started a new subscription for PACG starting from the S&S add-on deck. when checking my order (#3222807), I noticed it was still pending and the add-on deck has been put in backorder. Is there any estimation as to when a new batch of add-on decks are available and as such, when I can expect the shipping to start?
The Character Add-On decks are not on backorder. That is likely some kind of display glitch. The warehouse is still processing August subscription orders, and expects to be finished shipping around the 22nd, so you should see a shipping update by then.
Additionally, you can keep any eye on general August subscription and shipping updates here:
