Acer has a relatively standard return policy of 15 days for most of its hardware products (including laptops). Unfortunately, shipping will not be refunded and you'll also have to get a unique RMA number by contacting Acer customer support (see above) before you return the product. All returned products will also need all original packaging and any associated manuals.
Note that products purchased at a value of $2,999.99 to $4,999.99 will be subject to a 15% restocking fee, while items of $4,999.99 and above in value will be subject to a 25% restocking fee.
