I never received an email confirmation (like some people did) after reserving in the store on the morning of March 31. Here is what I did -
- go to Tesla.com and "My Tesla"
- On the login panel, click "Reset Password"
- Enter your email address used during in-store reservation
- Check email for link to reset password
- Click link and setup a password
- You will be logged in to your My Tesla account and will see the reservation(s)
