Tobacco is SO expensive relatively to most places in Europe and the US. I pay between 21-25GBP per 50grm tin, which seems high, but I really enjoy the blends I really enjoy

I, like you, tend to try new blends as and when I can. I have no more than a few 50grm tins put away - a couple from Europe which cost less than half in the UK, if you can find them. Looking at the US pricing Im quite envious but not enough to warrant emigrating, currently - not that you'd have me.
Thanks for your answers, I'll be 'collecting' more as I go.
