Well, just to throw my little bit in, here in Italy Erinmore Flake cost's 14 euros for 50g, as does the mixture.
I usually by it over the internet from a place in Spain, where it costs about €10.50, but I have lost a shipment once to Italian customs, so I'm a bit leery now (it was a bag of 20 tins!).
For years and years Frinmore flake was about the only tobacco I smoked, but eventually I got a bit fed up with rubbing it (it's one of the most difficult flakes I know to rub properly) and I couldn't get ready-rubbed where I lived, so I started buying the mixture.
Now, my everyday smoke is a 50/50 mix of the mixture and Condor ready rubbed. It's very good.
Then, if I'm feeling rich, I invest in a tin of Capstan Navy Cut Flake. Superb.
