Instructions unclear? Do I move to California before or after I cancel my subscription(s)?
I think in this case you just need to change your mailing address with them. There is a California law (and from other comments it looks like 4 other states) that requires them to allow easy cancelations to CA residents. And since it is probably too much work for them to prove you are a CA resident, they just have the logic check if your address is in CA to enable the online cancelation (since they have online signup)

It is not that `set -e` is bad, it is that bash is a bit weird in this area and you have to know when things eat errors and when they don't. This is not really changed by `set -e`: you already had to know them to make safe code. `set -e` does not wave a magic wand saying you don't have to understand bash error control.
But having `set -e` is almost universally better for people who do not understand it (and I would argue also for people who do). Without it you are responsible for implementing error handling on almost every line.
As other have already said: this is one of those things that generally pushes me to other languages (in my case often Python), as the error handling is much more intuitive, and much less tricky to get right.
