Why can't we buy less than 1000 apex coins?

I know that EA is trying it's best to make money from this, but seriously Respawn?

I currently have 500 apex coins and I don't really want to spend 10$ for 1000 apex coins just for the 350 apex coins that I need for the battlepass, this is seriously a big and annoying issue، by the end of the next season I'll have 900 apex coins and I don't even buy battlepasses! So why can't I just buy 100 apex coins instead of 1000 just for those 50 apex coins, Respawn?!? This is seriously bothering a huge amount of players, and you should be able to acknowledge it and make a change, because this is real people's money! And you don't even know how expensive 10$ can be in other countries other than America! Please consider changing this, Respawn. It'd help a lot of players out and I think it's worth the sacrifice.
