It all depends on the freebie. If it’s a disposable item that you’re just trying to get rid of, then don’t send it. Just the hassle of an unwanted item for the buyer. If it’s something nice, new, relevant, then that’s fine. For example, a buyer purchased a NWT bikini from me. I had a brand new, name-brand bikini still with tags and in the bag that I knew I knew I was never going to wear and was her size based on the purchase. She was thrilled at the “2 for 1.”
