[Suggestion] Icon/tooltip indicating if an item can be bought from a vendor

[Legion88]

Do you know this: Libra Eorzea
This is the official app from SE for smartphones and such devices, IT IS PART OF THE GAME.
They give you the possibility to get all info you need to find most items ingame with their own app for the game and it doesn't cost anything.

Or just use xivdb, the best database for this game.

In the end it boils down to "I have a item, you want it and how much are you willing to do or pay for it?".
If you are not willing to do anything (google search, Libra, XIVDB, dungeon farms, gathering, crafting, leveling, ...) you have to pay the price the salesman set or you just don't get it at all.
