They sometimes sell them in the photo area. IF YOU REALLY WANT BINOCULARS BRING YOUR OWN.
The ship will have maybe one model for sale at an overpriced rate.
You should really try out binoculars before you buy. Expect to pay a MINIMUM of $100, $150+ is better. Best bet for binoculars these days is a large sports store like Cabela's. If there is a really large photography store near you that might also work.
A good website to look at, just to see what exists, All Binoculars Official Site (telescope.com)
I have bought telescopes through them.
