I can not and should not complain. Normally, the merchants (only one in Nuremberg), the cartridge costs about 8 euros. I could also use cheap lighters. It depends on the same thing. The tobacconist gives me more per month lighters that I need for my life smoking. Fire was the same fire. But luxury is paid. If one wants to use his St. Dupont then asked to pay. Man (n) should be but reasonable: why a Dupont? It's all a matter of opinion. My Dupont is my sanctuary from the Foreign Legion and I use it for 20 years. Every day. The gas for filling hällt to 3 months. So I use 3-4 cartridges per year. Those are my 15 euros per year value (which I can blow for 3 suitcases tobacco or so in shortening). 3 Eurotiks for a cartridge is more than ok. Who wants to save on his Dupont, may also use the flints than Biofeuer. But who has a St. Dupont and used daily, focuses on luxury and do not look at the 3 euros per cartridge which is really cheap for this luxury. It's as if his Montblanc filled with cheap ink.
