What is going on with juices and percentages?

So ive been making my own juice for close to a year and ive always preferred melon, strawberry, litchi etc. fruity has been my thing. the first i made was 50/50 2% flavour 3mg. enjoyed it every hour of everyday as i refined my taste

as time went by and finances improved i thought id try "premium". asked around for the best store, tested their samples for almost an hour, bought 2 or 3 expensive bottles (about 300% of normal price) from a premium store. damn was this disappointing.

1. The price is the immediate shocker, even the cheaper ones. where im from i can make 100ml for about $7, less if you buy in bulk. these basic juices sell 30ml for $15. "basic" as in not steeped in the gardens of venus.
2. The kick/satisfaction is non existent. as an ex smoker i want the kick or rather the rush of satisfaction i got from cigarettes. bought juices dont provide this at all. you get no satisfaction, no kick, no rush, so breeze, no wave, just puff. it may be a gigantic cloud of puff but just puff. almost the feeling youd get if you vaped clouds without the damp.
3. The flavour is usually 10% or more! vaping this provides a deafning punch of sweetness and over saturation of flavour. my goodness i thought i was vaping haribos. and the combinations my god. vanilla,lemon, cookie, caramel, kiwi and a dash of some hippe name. my first thought trying this was abort.
4. The bottles. oh my word. i am this close to kill someone with this useless fucking ant sized spout in rock hard plastic bottles. and if youre lucky you get a spout. best thing is no top is standard, all different sizes and skrews.

I dont know why and I dont know how, but this is what people do. I tried i honestly tried.
