I bought too much of a product that was on sale. Can I resell it on Amazon?

I bought a bunch of the same branded product that was on sale and I want to see if I can resell it on Amazon. By branded product, I mean that of someone else’s esrtablished brand, like Nerf gun toy.

Currently the Branded store on Amazon doesn’t list the specific product online. Will I have the option to list their products or am I only allowed to resell products that they have listed?

This is just for a fun personal learning experience. At the end, I do plan to give away extra products to a school or institution though.
