Where to watch live?

Anyone know where/how to watch bachelorette episodes live for free/cheap?

We have ABC thru my roommate's family account but it won't let us watch live (error message says something like "your home wifi isn't connected to your ABC account" which I assume means it's because we're not the household paying for the subscription?)

We usually watch next day on Hulu, but would rather not have to wait and risk spoilers for this week's episodes and the finale.
