[Grammar] ‘price of’ versus ‘price for’

[northpath]

Is there any difference between usage of ‘price of’ and ‘price for’?
For example:
the average price of a book
Prices of oil rose by 10% in July.
And
We agreed on a price for the bike.

[GoesStation]

All of your examples would be unnatural if you swapped of and for,​ although the first would be less so. I'm afraid I can't think of an explanation for this, though!

 

[emsr2d2]

We usually say "The price of oil ...", not "Prices of oil ...".

 

[jutfrank]

You are asking about the normal difference in meaning/use between the prepositions of and for. The word price has no special effect on which to use. Compare the following similar examples:

What's the name of your baby?
Do you have a name for your baby?
