So thanks to TheExile, a Wind Trader at the Consortium forums, I've recently gotten the bug to revisit my transmog groups, and I'm currently in the process of creating an additional list of items that I'm going to (at least try) and do something pretty "revolutionary" with, and have people 'beta test' it out before I release it as my default list. The method I'm using to do this is not for the feint of heart, and will take me at least a week (mostly because of work time constraints), but I'm really excited on revamping and adding many items to my transmog lists, and having all your feedback on it, but that's for another day (PS you can follow TheExile on Twitter here).
Inflating Transmog Prices
While going through this process of revamping my transmog lists, I had a bit of an interesting thought. That is, with many of us using region wide pricing, and marking prices up above 100%, are we artificially inflating prices for super rare transmog sets such as Jade/Exalted etc.?
We see this effect very often if we are the only sellers of a particular item on our realm and we use a % of realm price to sell it. A sort of "compounding interest" problem. Unchecked, the price for this item will grow exponentially until it hits gold cap and errors out. The question is, is the same sort of process happening for these rare xmog items, and the answer may (or may not, gasp!) surprise you.
So of course I went to data to see if my hypothesis checks out or not, here's the selection of what I looked at to try to determine if we are having an adverse effect on the prices (which actually benefits us, but may inflate prices too high):

What I gather from this data is that my hypothesis is clearly incorrect. Prices have gone up and down over time, but have never gone up a considerable amount.
On the other hand, fairly regularly across the board, the quantity available has risen over time. This is most likely due to the pricing, that takes levelers out of the purchasing market (and rightfully so), but also leads to unbought items on certain realms that will be looted again before they sell.
I cannot say that it's been an issue on most realms, but I'd imagine that over time supply will outpace demand and prices hopefully will compensate so that we get more sales, and don't get inundated with inordinate amount of xmog gear, and can still sell at a fair market determined price that's profitable for us.
