I'm with Vipod, you should have been here in the early days.
I think the prices have dropped over the years with better juices hitting the market daily.
The biggest difference is the addition of premium juices. When I started vaping there was about 5 Canadian juice makers and they were about double what China was making and so much better tasting.
A vapers tastes have evolved like the devices we use and cost have gone up due to demand. With that demand, governing bodies have made it more difficult for vendors to get their supplies this making it more expensive for them and in turn you.
Don't expect juice to get cheaper, if legislation gets tougher the processes will be more expensive, but it will weed out the bathtub brewers giving you a better product.
I may be wrong but it's just my 2 cents
