I need an idiom for two things being very different in amount (price) for negotiating.
I’m trying to remember something along the lines of moon and ground/sky and ground, but I can’t remember the exact idiom/phrase.
The point is to highlight two prices being very different (one very high the other one very low)
Tried googling it but found nothing.
It’s really simple I just can’t remember it.
EDIT: context, I want to say “The price is negotiable, as long as it’s not ________ and __________, where the first is something really high and the other one is something really low, to highlight the difference. Hopefully that make it clearer.
