Why is it so hard to order replacements parts?

Hey everyone,

I'm a little bit annoyed to be honest with flipper and I seek a way to find good replacements parts for the flipper zero.

Let me explain, I wanted to buy replacements part for flipper zero but they're kinda hiding it:

You have to google it, and you won't find it on their website, next problem is that they won't allow you to buy a freaking replacement part with an accessory. When contacting support they will just tell you to make separate order, like duh obviously why didn't I think about paying 28eur for a top case flipper zero and 19eur for three little screen protector (10eur transport fee).

So is there someone who know where to buy a somewhat affordable replacement part for the plastic screen?
