Need help in detecting new content and notifications

[Unrepentant-Atheist]

So I'm trying to keep me up to date on new free games from https://www.reddit.com/r/gamedeals/new.json?limit=50 like this:

But I'm not really getting the desired results. I'm getting notifications whenever anything new is posted there. Even if I put free and 100% in extracting text, I'd get like 3-4 lines with either 100% or free, which is correct, but when new stuff is posted this extracted 100% or free gets moved around and it triggers new notifications.

What I really want is compare snapshot x(now) to y(old), if new line or new text with 100% or free appears AND is different to snapshot y THEN trigger.

Not if it moves around, not if it's the same as before.

A current snapshot looks like that:

The diff looks like this and still triggers notifications:
