The LGS I use, GT Distributors, always provides all of the boxes, wrappers, contents, etc. to me on transferred firearms, long guns and hand guns, and asks if I want them, or if I want them to dispose of them. Oddly enough, a local gun store, Academy, that we bought brand new firearms from, and had to return for warranty repairs told us not to worry about a box, as they would find one to ship the firearms (long guns) back to the factory. The factory always returned the long guns to the store in a factory fresh shipping box.
