Totally wrong. It's shipped in plastic bottles -- you don't want to store it in plastic, but in dark glass, so the size of what you buy is irrelevant. It's also dumb to buy the strength you vape, since you have to add flavors anyway; if you buy low strength, you're paying top dollar for someone else's PG/VG. The BEST way to buy it is 100mg; the size of the bottle should only be dicated by 1) your budget, and 2) how many glass bottles you have in which to pour it -- I freezer-store mine in 30ml brown glass bottles, for the reason you stated -- so that once a bottle is opened, it doesn't take me long to use it up; once it's been opened and I'm using out of it, I store it in the fridge.

Some of the MFS nic is shipped in brown glass bottles.
The cheap litres come in plastic.
Lately I been using MFS because it has the best price, and its good nicotine. Nicotine is suppose to be flavorless which is why I dont get why people claim they have bought the best when paying over twice as much from another nic supplier but anyhow, the liters I get from MFS always comes in plastic bottles and I break them down into 4 250ml amber glass bottles and then freeze them. When I need nicotine I will get a bottle out, let it warm up a bit and then pour it into 3 100 ml bottles and place 2 of them back into the freezer while using one of them. It works for me.
