Is Vial Running: Profitable?

This idea was introduced to me not to long ago:
Buy vials of water from Shilo general store at 11gp each, sell on G.E. for around 85gp each. They sell on the G.E. almost instantly and it is pure profit.
But is this really worth it? It requires constant attention (you must have your character run back and forth, over and over…and over and over). In about 10 minutes i accumulated around 500 vials of water and sold for about 40k over the G.E., with 5.5k of expenses. Every time you bank 27 vials of water you gain about 2k through selling them at the G.E. (it is roughly 2,349 gp – 297 gp cost of vials = 2,052 gp gain every run)
Sure, it sounds like fast money, but that is all it is. Running around for some extra cash. I have to say this is not how I like to get money. Fishing in the fishing guild or cutting yews is much more rewarding. Close banks, level gains, and high prices on lobs / yews make them better than vial running. A full inventory of lobsters takes me around 5 minutes, give or take a few extra minutes. Right now the market price on raw lobsters is 272 gp, meaning every load is worth 7,344 gp. Sure, it is slower, but it takes a hell of a lot less effort to have your character sit there and fish rather than run back and forth between the store and bank.
If you do have the patience to vial run, then enjoy your profits. There are easier ways to make money though.
