Help me find: ACID 5 Robusto?

So I found I really like the ACID One. I'd like to try some of the other higher end ACID cigars.

The two on the top of my list are the Acid Opulence 3 which I can find, but I'm having trouble finding the ACID 5 Robusto. I either want to get a fiver, or if I can find it under $100 I'll get a whole box to try.

I've called all my B&M shops and hit google, and I can find a few overpriced boxes of the ACID 5, but no fivers or good deals on a box.

Anyone know where I can find some, or any shops I can call that would ship to me?

TIA
