Neither; payment goes to Uship at time a bid is accepted. I think either of you can pay for shipment if you give them the shipment number. In my experience as a breeder, buyer usually pays for shipping, but you can negotiate payment (or repayment) with the buyer. Either sender or receiver is free to offer a gratuity. From personal experience, I would suggest a lightweight collar on the puppy and a METAL leash; I brought one of my girls home from Ohio to CT as a four-month-old with a cloth leash on her, and when I arrived home and opened the crate, she had chewed through the leash and ran for it!
