Issue 1 is just being released this week. Perhaps next week or the following week the mag will show up on discount sites? I don't know how these things work with comics.
Also, when searching, make sure you're not getting the Gold Key DS Digest thing, subtitled "The Interrupted Journey." My local shop inadvertently ordered one of those when I first asked them to hold issue 1 of the Dynamite comic for me. When I said I didn't want the Joe Certa horror, they just put it out on the shelf so luckily I did not have to pay for it.
Best,
