Ethelsimmons, Are you looking for spice blends?
Yeah they can be hard to find ones that strike your fancy but never be afraid to tweek them to your personal liking.
As others have said Penzeys has several nice blends and they have nice prices.
McCormick is another that has many nice spice blends.

Trial and tweeking to find what you and yours enjoy is what spicing is all about and I wish you well on your journey.
