Our Rewe carries it (.99 Euros); dm (.75 Euros), and I believe our Rossmann and Edeka do too. If you don't find it locally, PM me and I'll trade for some Tüff herb. :)
On the original question: not addicted, but most definitely one of my all-time favorites. Great performer, best value for money, and, to me, a pleasant scent. Not sophisticated, but down to earth, clean, straight.
I stockpiled five or six, in case they will ever be discontinued. And I guess I will add on... ;)
