Return Policy
Thank you for shopping at computerg.shop. If you're not entirely happy with your order, we're here to help — here's how returns, exchanges and refunds work.
Part A — Standard Returns stocked items
Eligibility — initiate a return within 14 days of receiving your order. The item must be unused and in its original factory-sealed packaging (anti-tamper seals and shrink-wrap intact), with all accessories, manuals and promotional materials included.
Restocking fee — a 25% fee applies to eligible returns (inspection, testing and repackaging). It's waived when:

- ✓The product was shipped in error by us

Part B — Items Available to Order not held in local stock
Items labelled Available to Order are sourced from our supplier specifically for your order, after payment clears. Because they're ordered on your behalf, return terms differ:

- ›Defects or transit damage must be reported within 48 hours of delivery, with photo evidence.
- ›Other hardware faults within the warranty period — see the Warranty Policy tab.
- ›At checkout you confirm you've read and accepted these terms before ordering.
