I checked out the local Five Below and they had 50 packs of comic books, every single one of which had Original Sin #1. Oh well.
So here's what I found... I was able to spot 3 types of packs. 1 had the ASM on the outside, plain as day.
The next variation that I nabbed at least 5 of was with a Defenders #1 1/50 variant on one side, and an Elektra #4 1/50 variant on the other side. Those have the ASM inside, which is still pretty obvious if you look at their bindings.
The other variation was with one of those Oz books (Skottie Young cover) on the outside, and a FFin #16 on the other side. Those also have the ASM book tucked in between...
Unfortunately those Original Sin packs don't have the ASM book. I saw plenty of those packs as well..
For what its worth the employee at the 5 Below said they do not keep a back stock on those. Whatever they have is placed out on the floor.
Group shot:
All but one are 9.8's. One of the packs that had the book on the outside cover is the one with the slightly dinged bottom spine-side corner. Definitely best to get the packs that have it sandwiched in the middle.
