........And what drives up the increase in prices we have observed when (if anything) a maturing business and technological advances will have likely led to efficiencies in wholesale production, distribution, and sale of the product?
What increases and where?.. it's certainly not with TW, Red Label Premixed Eliquid is £19.99 per bottle.... exactly the same price as when I bought my first bottle in May 2009.. so in real terms it's gone down in price.
The Platinum Ice is now cheaper than it was originally and you get 50ml not 30ml's. My first Titan full kit was £50, my first SD kit was £99.
There is an issue of consistency, reliability and quality that TW is now investing in.
