Be careful with cheap spices. If it’s from a trusted brand, sure, go for it. Whole spices tend to be more trustworthy than powders (and sometimes cheaper). But there have been some instances of heavy metal contamination of cheap powdered spices.

Cheap cinnamon is usually Cassia cinnamon, which contains high levels of coumarin, a blood thinner. Real cinnamon is Ceylon, and has much lower levels.

I like getting spices from stores with a bulk spices section. If e.g., you need a tbsp of cinnamon, or a single star anise, etc… you put only what you need in a little container. it will be super cheap compared to a whole prepackaged container and you’ll always have a fresh product with no waste. You can even bring/reuse your own containers! A lot of local food co-ops have a bulk area with spices. Frontier is a popular vendor for these, and their stuff is vetted and super high quality. Best of both worlds IMO.
