This guy seems to have decent pricing and good product.

From my experience. Traeger has a lot of filler. Used them and not a big fan. GMG are a little better. I'd be interested in the Lumberjack pellets. I would pay more for 100% wood.

How many bags per pallet? 50(ish) bags?

At $20-$25, for a 40lb bag, I'd be in for 6-8 bags. I can't store more than that right now but use them pretty regularly.
