Absolutely. Over the years I have tried and been disappointed with several blends to the point that when I find one that really clicks then I want to have a supply of it for the future.
I am a big fan of GL Pease blends and many great ones of his are on the chopping block. If I can buy some to put away for aging, why not?
I have put all my spare money to acquiring post 2/07 tobaccos I am in love with (about 4 or 5 blends) to the point where I have notg bought an actual pipe in years but order tobacco about every 3 months.
