Can someone clarify perfume?

[Jato Jay]

In the Pathfinder Campaign Setting (and maybe other sources as well) there is an item called perfume, exotic which adds a +2 circumstance bonus to diplomacy checks. The item descriptions says that perfumes come in vials which contain 10 uses, but the pricing for said item is listed as 100gp/dose (not per vial).

So, my question is, does this mean 1 vial, containing 10 uses is 100gp? Or does a single use cost 100gp, meaning a vial of 10 uses would be 1000gp?

I know this seems like a very basic question, but the language is unclear. Any help is appreciated!

Speaking just for me, I'd treat it as price per vial. That's how I've always handled it, that's how I've always seen it handled.

per vial, there are "love potions" for about 100g too, so I think it fits
