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

[Lukha]

...I don't see anything wrong with charging a premium for the convenience of being able to buy an item on the marketboard instead of having to hoof it all the way to the vendor to buy it yourself, nor do I see how this is in any way different from charging a premium for gatherable items. If you don't like the prices the item is listed at, then run to the vendor yourself and pay less. If you're too lazy to do that, and have gil to burn, then I did you a favor by posting the item on the MB so you didn't have to move more than a foot from your usual crafting spot to get it.

That applies just as much, if not more, than if you're too lazy to look the item up or ask your FC if and where it might be purchased. You're unwilling to expend the bare minimum of effort (especially considering that there's no way to play the game that doesn't also offer an internet browser that can be easily be swapped to for a moment), so you pay for that.

Yes there is. Everyone playing on PS3 or PS4 needs a secondary device to look stuff up. Nether console has a browser that's actually usable. I don't always have my laptop with me, and rarely want to go to the other room and boot up the computer just to look up an item I want to buy. If I happen to have my iPod on me, I may look stuff up in its Libra Eorzea app, but if I left it upstairs, I'm not likely to leave the game and go get it just to look up every item I buy.

The browsers may not be awesome but they are perfectly functional for the relatively untaxing task of googling an item.

Even if they weren't, you just proved my original point; whatever the reason for it, if you decline to check whether the item can be purchased at a vendor then you're making the decision to pay the convenience fee I charge for providing you the ability to simply obtain it from the marketboard. Nothing is preventing you from doing so, so obviously it wasn't that important to you. It's no different than the person who chooses to buy a mat they could easily go gather for free.
