That reminds me of a funny (embarrassing?) story... US used to clear out unused new condition, obsolete inventory service items online. (They gave away or sold ridiculously cheap some more durable items, like beverage carts, over the years too.)

One of the items I bought years ago was an unused duvet from US's short lived International First Class product. (For anyone scratching their head, yes, the original US A330s had 3 cabin classes when delivered.) Anyway, I haven't seen too many unique service items from that product floating out there over the years, so I kind of appreciate the nostalgia of that duvet.
