You could save even more money by just quitting altogether. Cigarettes you roll yourself also have absolutly no filter so they are even more dangerous to your health.
I have been rolling my own cigarettes for years. I dont do it just to save money, I do it because they taste better. I dont like "ready mades" People think bransds like Marlboro etc are high quality but they are not. The tobacco is dried out and to me they taste bad.
