Green Blender Smoothie Subscription
GreenBlender is a smoothie delivery service. Each week, members receive original smoothie recipes and pre-portioned ingredients to make smoothies at home. The only thing you'll need at home is a smoothie blender.
Whilst they do offer a gift card, they can set up a gift subscription if you get in contact, see the notes in their frequently asked questions for more details. In the FAQ you'll also find information about their delivery area which doesn't cover all of the USA yet, so check that out too.
