Any synth that sells to npc for a good price or god forbid actually gets you a profit is a god send. Read guides and do as much research as you can on prices (how much can you buy/sell ingredients/result, to/from npc's/guild merchants/AH, are city AH's cheaper/more supply etc.) and work it out.
Also, don't forget that there's no point spending an hour to farm a stack of tiger fangs when you could farm something else for an hour and make enough money to buy two stacks. The only reason you should ever farm your ingredients directly is if it's the only way you can get enough of a supply.
