You might want to avoid shipping notebooks via USPS after reading a story over at the Consumerist. A USPS customer shipped his friend five notebooks and insured them for $3,000. The package never showed up across the country, so he filed an insurance claim. The USPS gave the customer $74 for the lost ThinkPads.
Nobody knows what happened to the package and USPS’s tracking system shows that it never even left the Florida shipping center.
There are several other USPS customers complaining of similar treatment in the comments section on the blog post.
