I'm looking at the Pixel 128GB when I am signed in to self serve vs. when I am not signed in. When I am NOT signed in, it shows there would be a $300 activation credit. In that case, I know that if I were to cancel my plan at some point, I would be on the hook for the remainder of the tab balance but not the activation credit.
However, when I'm signed in, it shows $400 (instead of $300) described as "Additional offer discount" on the checkout page, and I'm assuming there is some extra $100 deal I get for being an existing customer or something like that. But, I am wondering if I decide to cancel my plan at some point in the next 24 months, will I be on the hook for any or all of this $400 discount? Is it the same as with the activation credit, which you are not on the hook for if you cancel?
