This seems fair, and is basically what I do. As I said above, it is as if you tried it in a shop. They will (or should) sanitise it and put it back on the shelf. Shops don't charge for that. With online selling, once you take out the shipping (as you mentioned) the only loss is the time and inconvenience of the accounting work in regard to stock and credit note.In the case of regularly stocked items, if it is returned in pristine, re-sellable condition, full refund.
