Clearance items are items that we choose to significantly discount for your benefit. Typically, clearance items are items discontinued by the manufacturer and that we have a limited supply remaining in stock. Due to the nature of clearance items, all clearance item sales are final and are not returnable.
We offer promotions and discounts to our customers on a regular basis. If we have any promotions currently running you may view them at the top of our home page www.TerahertzStore.com.
When you purchase an item, you are also given the opportunity to provide your e-mail address to receive coupon codes and updates on limited offers. This is a great way to stay informed of upcoming promotions and deals. Only One coupon code may be used per order.
