Actually right now skeletal K9's aren't available. They're a seasonal item only available Sept/Oct. I'm not sure where you saw it on the website that it's only available through DA though? it says slots are taken through our journals, but it's during that time of year only.
There aren't any current journals for them right now. Before we open we'll post journals warning people to get ready, and then post another journal when we open for round 1, then another for round 2, etc etc. We can only take so many, because the mold dies awfully fast. We still have to remake the mold from the last batch, before we can offer them again this year.
