Seems to me there is a LOT of stocking up happening here, which may result in juices running out again quickly.
I've seen it before with stationery supplies at work. When items are scarce, people tend to grab a stockpile when new supplies come in, so suddenly we're out of stock again, which compounds people's fear of running out, so next delivery they stock up even more (guilty as charged). People are actively encouraging newbies like me to stockpile at least 6 months' worth of
juice, which isn't easy when you're still finding your flavours/nic strength.
