Yeah, it would possible make sense to ship 2 if one gets lost or so.
Even if it is fair etc. it’s “just” a glass.
You can buy a whole FP3 battery for that price, or a 1/3 of a whole new display.
I think the relations are a little off here.
The same goes for the back cover though, that is nearly as expensive as the screen protection – and it’s just plastic.
Also given screen protection from physical influence is not requires/useless, as people said earlier, they should really be marketing it in a way that it’s only a tool for privacy or blue-light filtering, which they seem to do.
Only this sentence is a little off:
Our privacy screen protector serves double duty to keep your display in pristine condition while also ensuring that no one can see what’s on your screen but you.
