Generally made to order means that they make it as soon as you order it. That in mind, some juices need to steep in order to achieve its full flavor potential. I DIY my own juices, I use no more than 15% flavoring and I generally make 80 vg juices, I also let my juices steep for about 2weeks to a month before vaping it. Easy solution, if you do enjoy their juices, is to cycle. Buy a good amount of juice to last you 2 weeks, wait 2 weeks. When you start vaping that, buy more to last you another 2 weeks, by the time your juice is done, the next batch is ready to vape, then you buy more. So on and so on.
Hope that helps.
