Most unopened items sold by Melrose Inc. in new condition and returned within 30 days will receive a refund or exchange. The return window for items sold online begins once the order has been invoiced. Invoicing happens when any part of the order is shipped, delivered by a courier service or made ready for pick up.

Software is not returnable and not refundable. All sales are final. This is generally part of all webcarts selling software. It is buyer beware. The reason for this is once an end-user customer sees a License Code then that code is 'spoiled' because they can use it to gain access to the software.  Once a License Code is registered by a customer that product is available to that customer and therefore the code cannot be returned.
