Is my cost to do a return shipment considered a business expense?

Dumb question probably, but it's come up and I'm not sure how to handle it.

 

I purchased supplies for my self-employed occupation and I am doing an exchange with the company to return product that didn't work for my use case with something else that will. We made it a new order to keep my taxes clearer, and they will process a return on the original order. However, I paid for return shipping of the original supplies myself - my question is whether I am able to put this on my expenses for the business since it was business related? I have a receipt for it and all.

 

Thanks!
