Flaviar club will let you sample different juices. My wife got it for me last Christmas. I love it.
Stayed in a Whiskey, Whisky, Bourbon themed hotwl about a year ago. In the bar they had hundreds of different juices. Was amazing just sitting back by the fire doung all sorts of 2oz sampling.
Flaviar has a great selection and, on the whole, their pricing is pretty good. Some of the “Vault” stuff is a little optimistically priced but most of the regular fare is at or near local pricing for me.
