They also have various rewards and loyalty programs, which is kind of neat... AND, if anyone is interested, I can use their website to send you a $5 coupon (aka "certificate"). Just comment or email me and let me know what email address to use when sending the coupon.
It's not quite the same as going into a store and being able to smell (and sometimes taste) the teas yourself, but that's why they have sample sizes and customer reviews. :)
