I do buy large containers of garlic powder, black pepper, and onion powder at Sam's Club because we seem to go through these pretty quickly. I also buy cinnamon in a large container because we also use quite a bit of that.

I have found that good buys on spices and seasonings can be found in unexpected places. Drugstores and 99 cent stores often have really good prices, but rarely advertise them. Also, go on a treasure hunt at most grocery stores and supermarkets for a display of little clear plastic hanging bags. I know they have these at Save Mart. Sometimes they are in the produce department, sometimes the ethnic foods aisle, sometimes with the baking and spices. Mojave is a brand I have used often. They are small quantities, good quality and terrific prices. If you have any leftover, transfer to small spice bottles you have recycled from previous purchases, or just roll up the bag and secure with a rubber band. Be sure to label!
