I like a little creativity with my tea. Pretty packaging is a nice touch, but I'd rather have a pretty product in my cup than risk it for packaging. See if there's anything unique you can do to show your investment in the customer without risking the quality of your product.
About 60% of the reason I buy anything is due to the way it's packaged. I'm really attracted to pretty boxes, tea bags, and tins, but I think this is more important for at-location customers, since it appeals more to impulsiveness rather than research of product.
