I found a deal on a Kindle with special offers that I want to send to someone for a gift. I don't have access to their Amazon account. Can I send them something like a voucher to remove (or just outright remove) the special offers for that Kindle for their account, without having access to their account? Is there some other way to remove the offers from the device without having access to their account? It's a Kindle Voyage, if it matters.
