It's definitely possible there's something shady going on.
It's also possible that Vaposhop preordered just like the rest of us. We know HL was offering retail packages during the indiegogo campaign, and I'm sure they were still interested in working with retailers once they opened up preorders.
From what I understand Vapefiend was a backer, and is still waiting on the rest of its order, even though non-retail backers are all fulfilled and preorders have been going out for some time.
So you could even say that HL is prioritizing individual customers over retailers at this point in time.
Purchasing a Grasshopper requires patience. I've been passing the time watching kung fu videos.
