Hi @brianna8!
You’ve got some great recommendations already. Adding to the pile, I’ve ordered numerous herbal tinctures from Herb Pharm- everything I’ve got has been very high quality. I also like Mountain Rose Herbs for herbs and teas (although they are pricey, the quality is high).
That being said, if you’re looking for herbs, plants, and other herbal products, the best place to go is to a local herbalist or apothecary if you have one! They can not only connect you with great and fresh plants, they can also give you lots of advice about how to use your herbs too 
There’s also the list of Coven Member Shops - lots of great places for various spiritual and witchy goods! The Recommendations category of the forum is another good place to browse around (you can use the search tool to find exactly what you are looking for) 
Good luck and happy shopping!
