Micro Center Return Policy:

We guarantee your satisfaction on every product we sell with a full refund — and you won’t even need a receipt.* We want you to be satisfied with your Micro Center purchase. However, if you need help or need to return an item, we’re here for you!

If an item you have purchased from us is not working as expected, please visit one of our in-store Knowledge Experts for free help, where they can solve your problem or even exchange the item for a product that better suits your needs.

If you need to return an item, simply bring it back to any Micro Center store for a full refund or exchange.

*If you are a Micro Center Insider or if you have provided us with validated contact information (name, address, email address), you won’t even need your receipt.

Desktop / notebook computers, tablets, processors, motherboards, digital cameras, camcorders and projectors, 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.

Refunds will be credited to the credit card or debit card account used for the original purchase.
