Do I have to use the shipping label PC swaps provides?

PC swaps always recommends using the shipping labels we provide; however, if you find a better deal on shipping or decide to pay for the shipping out of pocket, we will reimburse you what the buyer paid for shipping. If you ship using your own label, PC swaps requires a receipt from the carrier and a tracking number to provide reimbursement and update the tracking in the buyer-seller messaging.
