newuser2019
I was looking at a free Skillshare video and thought about signing up. Because I didn't actually commit to paying up right there and then they sent me an email with a code to get two free months (newuser2019 - 2 free months).
This gets you two months access to everything on their site for free (I know as I just used it) but you'll need to enter you CC details, however, you won't get charged until your two months are up so >>you just have to make sure you cancel your account before then if you don't want to get charged.<<
That last bit is important - put a reminder on your phone to remind you to cancel your account before the two month trial is up otherwise you'll have to pay.
