Courier of shopee will give 3x and wil lcontact you 3x before they tag the item as failed. Return system to failed delivery is relatively fast. Courier are friendly and delivers the item that you order. Shopee is cheaper maybe because they only charge 1.5 percent to seller unlike lazada who has lots of hidden charges that can go up as high as 5 percent. App is easy to use even if you are a seller and they has an option button for the colors that you like. So you rarely need customer service to assist you
