My company Christmas present arrived today. It was a cute little solar panel that you can plug into your mobile phone to charge it.
Unfortunately, the person in charge of sending the gift to Spain had this weird idea that you should actually be truthful on the customs declaration, and wrote "electronics" with value of $5 on the form.
Spanish customs charged 0.50 euros in customs plus a 20 euro "processing fee".
Just put "other" as the description with a value of $1. Works much better.
