The parties to whom your surplus stock is sold mainly comprise independent supermarket businesses. Stock is never sold to head offices. We assume you have already tried this yourself! Surplus stock is also sold to companies such as XENOS. It may be that you do not wish to sell some of your leftover stock via the supermarket channel, or that the excess items are too big to be sold via the usual channels. Companies such as XENOS are able to offer a way out.
