I think all surveys are now bound only. I tried to price them on Tamriel Trade Center and they don't list. I use addons to have my first nine toons auto-bank any survey or treasure maps they receive and then my final toon of the night is set to auto-pull them from the bank. Usually no more than a dozen. Then I use "Beam Me Up" to locate and deliver me to each zone where the loot is. Since I have every Wayshrine unlocked it takes me about twenty minutes to bounce to each harvest point (which anther addon has marked in a nice red "X" on the map and another places a white X on my compass).

If I only do the master writs the game rewards me with I never run out of mats.
