I was wondering what would be the best and cheapest way to send an iPhone charging cable (1m) from the US to the EU? To my understanding it should fit USPS "flats" and could be shipped by First-Class Mail International: "Our most affordable option for postcards, envelopes, and flats. Send anything up to 4 lbs (cannot exceed $400 in value) to more than 180 countries. From $1.15 at a Post Office." https://www.usps.com/international/mail-shipping-services.htm My family told, however, that USPS asked around $15 to ship this tiny item as a package...more than the item costs itself...? Any advices, experience? Can such items be shipped in "flats"? Are there any alternative mailing services?
