Does anyone have a recommendation/suggestion as to the most profitable vending machine? :)

they're not particularly profitable, but whatever shop has the newest released items in the News first, then Ocean Depths because it has a higher rarity limit.

Its true there isn't one thats going to make you suddenly rich. When I vend I go for machines for what I'm after at the time. Right now my main goal is to finish all the wardrobe achievements I can. So I vend where I can get wearable items. I sell the extras off or turn them in to other things, like thw recycle beast or power crystals.

So figure out what type of items you might need or want for achievement goals and bend accordingly.

has a great guide to items by machine.

the occasional books you can find are generally decent sellers to break even, and keeping an eye on whatever drops the needed items when achievements get put up involving older items. other than that, yeah, I'd say ocean depths. not as great when there's no chance at that legendary weapon anymore but has a decent variety.

I appreciate everyone'd feedback :)
