I've recently seen "I could take it or leave it" as a way of saying "it's not that important to me." For example,
Q: "I love the taste of pumpkin pie. How do you feel about it?"
A: "I could take it or leave it."
But I'm much more accustomed to hearing "take it or leave it" used in the form of an ultimatum, especially in a negotiation setting -
Buyer: "How much for the shoes?"
Buyer: "Will you take $50 for them?"
Seller: "I'd rather not go below $75."
Buyer: "I'll give you $60. Take it or leave it."
You know when you can't remember the name of that one guy in that movie, but you know that you know it? In the same way, I'm certain there's another (more correct) colloquial phrase to convey indifference without saying "I could take it or leave it" (and I've heard it before), but I can't remember what that is. Can anyone help me out?
It really just seems like "take it or leave it" has been improperly co-opted as a means to express indifference.
EDIT: After all of your inputs, I think I've remembered the statement I've been looking for.
"I could survive without it."
This may express more of a negative opinion of the thing in question than a neutral opinion, but it's definitely the phrase I have been seeking. Thanks all for your help.
