They are all on this site in some place or another. If you just want a list of stuff since February, here's two links that should cover everything:

That covers everything that is out from November of last year on. I am using that list to make sure that I make pages fro everything. As you might see from the red lines, there are a few not made yet, but the names are there.

That is a list of all upcoming issues. It does not currently include the stuff announced this month, but I will try to get on that soon. It has a lot more red links, because there are a bunch of pages still needed. Names and approximate prices are there which should help.

Personally, my comic book store has been told if it says Grimm Fairy Tales and it is from Zenescope, they are to order it for me. I get some of the ones that aren't Grimm Fairy Tale, such as The Jungle Book and Charmed (whenever they manage to start making more issues) and Salem's Daughter (if they ever get any more) and Sinbad (can we sense the pattern here). At least one of my favorite Zenescope characters, Nathan Cross, is getting some comic time.
