I'm in-between on if these will be difficult to obtain or not. On the one hand, there should be plenty because the club stuff rarely sells out. On the other hand, the positive press on these is off the scale.
Anyway, they tier their exclusives at three prices - paying member, free member, non-member. At the very least, Tek, I'd head on over to http://www.gijoeclub.com/
and become a Trooper (free membership). That will get you into the forums and some affiliation with what's going on.
In the long run, I'm thinking of joining anyway because it's only $40 to sign up. By itself, that'd be a lot, but the discounts are usually good for paying members and I'm betting that I'll save a good chunk of the $40 across the sets. Plus, you can get a free Big Lob or Urban Adevnturer (?) and then the magazine/newsletter if you're a paying member before the 16th.
