The ability to see all my data in one place, it's very easy for me as an environmental consultant/organizer of events etcetera! And I can always go back into any event or project that we have done with previous partners such has H&M (or even other companies) if there are problems later down-the line - everything is stored here so this helps avoid having multiple lists open at once!! Also really happy how quickly they respond when you email them questions / requests via support@greenstoryapparelcompany I like that it's easy to use, you can share easily with social media sites and people are able to see how much they've saved so far! It would be nice if there were more options for saving money as well as sharing savings. You should definitely try this out! We have been using it since we started our business and everyone loves seeing what they're doing towards being greener!
