I just want to add that if you are buying tins, you don't need the jars. (Except for after you open it to start smoking)
If you want to do up some jars, buy bulk.

Bulks to jar:
Peter Stokkebye Luxury Bullseye Flake
Dunhill Nightcap
Mac Baren Old Dark Fired ready rubbed
Samuel Gawith Full Virginia Flake
An aro that sounds good to you. I like H&H Vermont Meat Candy.
