Big Green Egg... tent.

I stopped into the local-chain hardware store where I bought my Eggs years ago, to get a couple of 1/4x20 screws.  On my way to the cashier I wandered thru the BGE display (I rarely go there anymore since switching lump) and there was a... tent!  It stood much taller than me, was roughly Egg-shaped, kept open by those elastic-loaded tubes that most tents are erected with these days, lots of clear vinyl windows, and lots of zippered screens (I failed to note if it had upper and lower vents).  
I'd never seen one of these before, nor remember anyone mentioning them here.  This display model was on sale, $230 regularly $530.  While writing this post I went to Googlez Imagez and typed in "Big Green Egg tent" and there were a lot of different pics, but what I saw today did not appear, anywhere!  
I figured with that huge discount it was an old product that they were getting rid of, but now I'm wondering.  Anyone seen one of these before?  If not, I'll go back on Monday and take a pic of it; it was rather unique.  (EDIT:  I'll also ask if they sell a Smokeware vestibule for it....)
