The cost is a little pricey but if anyone ever wants to do a mix and match combo of Lumberjack pellets in 1, 3, or 4 pound bags you can go here:
Mix n Match LJ Samples
I did the 7 pack sample bundle of the 1 bound bags to figure out what I liked and didn't like. I was also able to mix and match options to figure out custom blends I liked and didn't liked. This was nice to know that way I knew what to pick up and what to avoid when I bought big bags.
It is also nice if you want to try a wood you don't get easily in your area like Mesquite for beef!
Enjoy!
