I didn't either.
I'm pre-ordering the ones I want from Forbidden Planet online, £9.49 an issue.
How did you go about doing that? Is it on their website or did you contact them or just go in store?
I was going to go into my local WHSmith or comic shop and ask if they'll have them all in as I don't plan on spending 240ish quid a year on this as only interested in the main Starfleet vessels.
