I'm sure you've seen on popular tea websites option for joining a "tea of the month" club. While a fun option, usually this is for a year and can be pricey depending on the teas you wish to get (from basic to premium blends).
However, I recently found out there are tea subscription boxes just like my Nerd Block or Loot Crate subscriptions! Perhaps this would be a good option for your as well?
Some Wellness Subscriptions advertise the inclusion of tea leaves. However, I prefer to stick with my leaves instead of untried food items. I've already tried a few food boxes, and I was not overly impressed.
My first subscription is Timely Tea, a monthly box which advertises "a loose leaf tea subscription box sent straight to your doorstep! Enjoy 10-15 cups of three different flavors, a tea infuser, and tea goodies!" They offer up three samples & one goodie item.
My second subscription was to Teabox. They advertise "incredibly fresh & delicious teas
chosen to match your tastes using data science." Each box offers three samples. They come wrapped in fancy paper, and Teabox has a very well put together website that allows for
additional shopping, reviewing, and connects to their blog.
Timely Tea's website is very straight forward and is solely for starting a subscription. Teabox's website offers a shop to try different varieties of tea. It also allows you to review selections. I like Teabox's more interactive website and blog.
NOTE: I only kept my subscriptions a couple months. I find its better to know what your purchasing versus leaving it to chance (most times). While I sampled some teas I liked, I sampled more teas I disliked.
