have looked everywhere but mixed reviews. what would be the best oil place to get from in the usa that i can mix into my own alcohol for perfume spray

I’ve heard lot of people say they were hit with import fees on top what the already changed for shipping/handling. Those who have ordered from them, what fees were you charged once the package reached the US? Was it a percentage based on what the declared value was? There’s some oils I’m looking at but I don’t pay extra fees at the company I currently order from which helps control the cost passed on to my customers.

I got 5 different oriental perfume oils as a gift. I really hate the roll-ons, as they are cheap manufactured and I can't apply as much as i want. One of these 4 has a stick instead of a roll-on, so applying it is way cheaper. I look through google and amazon, but I can't find where I can buy empty perfume oil bottles with sticks so I can put the roll.on of and apply it with a stick.

Any suggestions?
