I have around 50 lbs. in my cellar and am slowing down on purchases. The 50 lbs. is for two smokers, and I don't feel it is excessive. I don't tend to buy tobaccos that are no longer manufactured, or very hard to get, but I have stocked up on some tobaccos whose availability is erratic, like S&G and G&H. I have cellared to ensure availability, both for short term and long term supply. I think there is a lot of uncertainty wrt taxes and restrictive legislation in the US and that too weighs in to my buying decisions.
