Depends where you are. Penzey's Spices can be mail-ordered, and they are the only spices I use. Always fresh and good quality, plus they sell in larger quantities. It costs the same for a big bag of spice as for a small jar. I buy in bulk and freeze the extra.
Winco sells cinnamon in bulk (I know, I buy it in bulk). Any grocery store should carry it, but if you are looking for a better quality cinnamon, try a natural foods store or spice store.
