Refund only when the item is sold out/unavailable.
Any item purchased from Castle IT Online Store may be returned for credit, provided that it is returned sealed (in its original, unopened, undamaged packaging, with all documentation, just as it left Castle IT Online Store), via appropriate shipping methods. If a unit is returned unsealed, any costs incurred in the recertification of that item to the condition stated on the original invoice, plus any applicable restock fees, will be deducted from any refund or will be invoiced to the customer. Recertification fees will apply to any unsealed units returned without regard as to whether the unit was actually installed or otherwise used. Castle IT Online Store reserves the rights to reject or refuse to refund if the item has been unsealed by the customer.
