Many, many blends are available only in tins. For long term storage, tins certainly take up less space. (We won't go into historic reasons for packaging that way.
) Bulks may be more economical, however.
Personally, I buy both. If a blend is available in bulk, and I am going to smoke it in the near future, I will buy it that way. But if I am planning on aging, I buy tins, simply because it takes up a lot less space.
This is all a matter of what works best for you. :
