You must contact Acer to receive a return merchandise authorization (RMA) before returning your product. Product arriving without an authorized RMA will not receive credit. All merchandise without an authorized RMA will be returned to the customer.
Unfortunately, you cannot change your shipping method after you submit your order. Orders with physical shipments are immediately sent to the Acer fulfillment facility when they are submitted and our system can no longer retrieve or change them.
It may take 1-2 business days to process an order. If you have an account set up with Acer Store, you can look up your order and see the shipping status from your account.
