Was offered a home demo, but...

A short time ago whilst I was wrestling what I could improve  in my system (budget wise), I came to the conclusion that having read and done my homework on a new DAC, the highly rated Ferrum Wandla, I saw that my preferred dealer dealt with them. After a couple of tentative E-Mails with him, I was offered the "demo" model he had, at a reasonable cost of £800 fully refundable deposit. I was going to accept, but having just had "something lost in the post", and my doubts about couriers in general being in my head, I had to decline, as I the only luck I get, is bad luck, and while I know nothing would have happened during transit (both ways), I felt very uneasy about the situation, as a slight scratch may cost me £800... Am I overthinking things and being to over cautious?

PS, I have had speakers shipped here on a pallet before, so its not as if I have not had a courier deliver Hi Fi before
