Full policy: Shipping Policy Full policy: Refund & Return Policy
Most items can be returned within 30 days of the delivery date for a refund or exchange, and every return needs an RMA number. For a full refund, items may be opened but must be unused, in original condition with all accessories and packaging, and any free promotional items must be included. Except for damaged, defective, or mis-shipped items, you pay return shipping. Items returned incomplete, used, or missing original packaging may be subject to a restocking fee of up to 15% or a partial refund. Special-order, custom-configured, and clearance/final-sale items, opened software, downloadable content, gift cards, opened consumables and personal-use items, and items missing serial numbers or manufacturer packaging can’t be returned. Any exceptions are noted on the product page.
Once we receive and inspect your return, we email you to confirm approval. Approved refunds go to your original payment method, typically within 3–5 business days of inspection, and your bank or card issuer may take an additional 5–10 business days to post the credit. Original shipping charges are non-refundable unless the item arrived damaged, defective, or was shipped in error.

Coverage, term, and claim process vary by product, condition, and manufacturer, so check the product listing and manufacturer documentation for the exact term. Open-box, refurbished, used, and final-sale items may have different terms.
