I am looking for sheet music for "Storybook Love" from the 1983 movie
The Princess Bride.

The comments in this answer, about out-of-print books that seem to
include this music might be helpful:

Perhaps a used bookseller or local library can track down these books...

I'm the one who posted the names of the two books of movie themes that
contain "Storybook Love," according to the songs listed in the
descriptions of the books in World Catalogue (I'd give you a link, but
it's a subscription service). On a whim, I checked an online used book
source I frequently use. Both books are actually listed--not many
copies of each, and prices are not cheap. However, Powell Books (see
the 2nd link) does have a copy of the second book for less than the
price you've posted for an answer.

If you want to search other online book services to compare prices and
availability, I've found bookfinder.com to be a useful tool.  Good
luck!
