General Return Policy
Desktop / notebook computers, tablets, processors, motherboards, digital cameras, camcorders and projectors, 3D printers, 3D scanners, and CD/DVD duplicators may be returned within 15 days of purchase. All other products may be returned within 30 days of purchase. Merchandise must be in new condition, with original carton / UPC, and all packaging / accessories / materials. If you need to return software, a game or a movie, remember that you may not retain any copies — it’s not legal, and it’s not nice.

Wireless phones and devices may be returned within 14 days of purchase. When returning a wireless phone or device with a plan, you are responsible for ensuring that your service is cancelled with the carrier. If you don’t cancel your service, you may incur additional charges from your carrier. All carrier charges are your responsibility.
All Digital Download sales are final and are not eligible for return or refund under the Micro Center Return Policy.
Using the software may require the use of a computer or other device that must meet minimum system requirements. It is recommended that you familiarize yourself with the system requirements before making your purchase. Software system requirements are typically found on the Product information specification page.
