Shopee will automatically cancel your orders if:
Sellers are required to ship out orders within their Days to Ship (DTS) period, excluding weekends and public holidays. A ready stock order must be shipped out within 1 day from the paid date. Products that are pre-ordered must be fulfilled within 7-30 days to fall within the DTS estimations.
To check your order’s shipping deadline, go to To Ship under My Purchases via the Me tab on Shopee App > Check the ship-by date under your order.
Once your order has been cancelled, the payment will be released back to you based on the payment method you used previously.
