If you hover over the locs it will even show you were the vendor is on the map.

wow i didnt even know that was a thing...thank you

:) It's new, and I just added it to the item pages this morning (prior to that the maps were only on NPC pages, and they've only been there for less than a month).

Also you're welcome, but I can't take all the credit: a great number of fellow players helped to "map" the zones to make that feature possible (and in fact there are still a number of zones that need to be mapped ...)

I haven't checked myself but do these vendors carry both Ring and Circle?

Yep, the vendor in Kelethin Ranger guild has both!
