At .55 a pack you’re beating my .75 per pack cost.
Locally tobacco prices vary by county and city but tubes are usually $2.50 a carton.
Mail me if you have a good online site for supplies.
That's filtered tubes. I use non-filtered (Athey brand) which were $1 per box of 400 tubes (I got 100 boxes i.e. 200 cartons, when I got them 6 months ago at Lil'brown Smoke Shack). I get bulk tobacco in 5 pound bags for ~$50-60 each at Tobacco General.
