Sometimes items are returned to NCT after the product has been discontinued. If NCT no longer carries an item that is sent in for replacement, or if that item is simply out of stock, the item will be sent to our Back-Order RMA Department. You will be notified via email with two options: either NCT can send you a comparable replacement item, or a refund of the current market value of the product will be issued. A current-market-value refund may not exceed the original invoice price. If the item is returned within 30 days of the original invoice date, a full refund will be issued.
