Hi there! Thank you this is helpful. I have a related question. Let's say I'm selling something whereby I would normally be making a profit on the item (for instance, sold for $15, and shipping cost $3), and let's say this is the case for most items I sell. But then let's say the buyer complained about this particular transaction and I had to refund the buyer, which means in the end I lost the shipping costs. Can I deduct the shipping costs, or still no because I didn't make any income at all from the transaction in the end?
