Not a big discount, but free shipping right now.

I don't usually have to worry about my laptop dying

Tank isn't even remotely close to the computer at my parents place either, never mind nobody in that house uses a desktop computer anymore. And I think all the powerbars are those Monster surge protector ones anyway.
I just want to cover my ass if the power goes out while people are at work.
Just permanently have 1 powerhead plugged into a UPS so when it does go out, it keeps going.

I have no issue spending $150 on a backup.
•1325 VA/810 W capacity
•Half/full 10 minute / 2 minute runtime

Part of my brain wants to say that a 5w power head would use 5w an hour, so a 810w UPS should power a single 5w powerhead for days.... But obviously that's not how it works lol.
