When you move overseas, wouldn't you take anything with sentimental value onboard with you as luggage? I can't imagine being too devastated to lose books or whatever other larger items people take when they relocate overseas (assuming that you would be compensated for the monetary value of lost items and be able to replace them). In my experience, most sentimental items are small enough to easily fit in a suitcase.

However, on second thought, I suppose some people would have more and larger sentimental items than I do, like large vases or antique pieces of furniture and so forth.

Is it possible to pay extra to have a very large flotation device attached to your shipping container? :P
