there are plenty other products out there where you can pay the money, receive an invoice, and still not get the product. its pretty normal.
i used to work in travel and we'd take full payment, issue them with all the paperwork, and still have the right to cancel anytime before travel. that's not a lot different to what he's done. he's cancelled before handing it over.
amazon did it a while ago too. when they took back all those ebooks that people had already bought and downloaded, and gave the money back.
