Love Penzey's!!! What a fun store. Whether you go in with certain spices in mind or just to browse, you're bound to leave with some awesome choices.
Most items come in multiple size options. I am in love with the tiny glass jars. If you use a lot of a certain spice/herb, you can purchase it in a larger bag and jar it yourself if you prefer (empty jars available). There is also a large selection of gift boxes so if you are trying to find a gift for someone who has everything or is difficult to shop for, these are excellent options.
The only drawback for me is that I don't believe they have any organic options. I didn't expect them to, given the size and that it's a specialty store. It isn't a dealbreaker for me, but for some it could be. Because I prefer to have the choice, I will probably continue to purchase my common spices at places like Whole Foods, but for more uncommon and fun mixes, I will shop here.
