I know the Aug/Sept 2017 issue is out there, but my local comic shop thinks that they're getting it in a couple of weeks
Have they landed at Barnes & Noble yet? Anywhere else?

Yes, I picked it up at a local sports card shop on July 27. The shop got a few copies the day before. I was in a Barnes & Noble last Monday (July 31) but it still had the Outlander issue. In my experience the week people start announcing that they got it through subscription or at local stores it turns up at B & N by the weekend following that weekend.

Made a stop at B&N and found it there
It's kinda funny to think of Buffy cards as "vintage" but some sets are almost 20 years old now.
I got Promo Card 4
