Many of the Latin translations of the Belgian-French series of Asterix comics are available through Amazon.com in the US, but they are less expensive if ordered through Amazon.de. For example, as of this writing, a typical volume costs nearly $40 in the US vs. 12 euro from Germany. Even adding shipping to my US address, ordering a volume from Germany cost only $20; if you order more than one book at once, the savings is even greater (e.g. $36 for 2 books). Of course, this is with the slowest shipping option from Germany.
