Assuming the price isn't astronomical, the best bargains are the blends you enjoy most. Pipe tobacco isn't a tool, a vehicle or food. You smoke it for your enjoyment. Pipe tobacco isn't utilitarian. If you're sacrificing enjoyment for a nickel per bowl, does that really make sense? Clearly, that had to be balanced with what one can afford. However, unless you're smoking significant volumes of tobacco each day, I think we're talking a few dollars per month.
A good point is made here.
Let’s say you are on a ship on the ocean.
There’s not a woman in two thousand miles either direction.
The only entertainment you have is a pipe and watching movies or a book or something else, but you can smoke your pipe 16/24.
Now, it’s hard to smoke a bowl an hour for 16 hours every day.
There are 42 grams in an ounce and a half of tobacco. That’s a lot of tobacco day after day.
But let’s say in 30 days you smoke 45 ounces of tobacco. Round it up to 48 ounces, that’s three pounds.
You buy the most expensive which sell for $100 a pound. That’s $300 a month.
If you smoke PS 400 Navy Flake or Newminster 400 without Perique two 1 1/2 pound boxes are $150.
But you can buy six pounds for $240, or $120 a month.
Or four 12 ounce bags of Smoker’s Pride for $60 on sale.
Per day, it’s all peanuts.
$10 a day at the most, and $2 at the least, three pounds a month.
It’s likely the cheapest vice other than coffee on earth.
Try smoking hand rolled cigars and run the numbers.
