Can add the Box to BackerKit?

Can I somehow (and  if so, how)  add the collectors box to my locked-in BackerKit order for OblivAeon?

Yes, but that will require Craig to unlock it! Shoot him an email at craig@greaterthangames.com some time the end of the month (he definitely won't get to it for the next few weeks due to Gen Con).

Still awaiting a response.

We're only just now starting to get caught up, so non-urgent requests like this are sometimes still pending. You can go ahead and shoot a follow up email to both of us and we'll make sure we get to it :)

And what is your email address?

If I recall his email is paul@greaterthangames.com

Okay.  It is unlocked.  How do I add the case, now?

Should I CANCEL the first order and do another pre-order?

I think that is the technique you'll need to employ, but I'm not 100% positive. Ask Craig if you have any questions :)
