Shopee Coins will only be accredited to your account after your order is completed - that is, after you have confirmed the receipt of your order.
Shopee Coins can be earned from any Shopee Preferred and Shopee Mall sellers (excluding purchases from the Tickets & Vouchers category).
If your order is underway but not completed yet, you can still see the amount of Shopee Coins attributed to this order, by checking your order details. To check your order details, go to your Me page > My Purchases. You will receive these Shopee Coins once your order status has shifted to Completed.
