Appliances Shipping Cost from Boston, Massachusetts to Bratislava

Shipping a 50 lb package costs roughly $40 to $90 for ground services, varying greatly by distance, carrier (USPS, UPS, FedEx), speed, and if you use flat rates or discounts, with USPS Ground Advantage often cheapest for shorter distances and FedEx/UPS competitive cross-country, plus potential surcharges for heavy items. For example, short-haul USPS might be ~$38, while cross-country UPS could reach ~$72 plus fees, or you could find FedEx Ground around $70.

Very generally, your national postal service will be the cheapest way to ship internationally. The Universal Postal Union has been in place since 1874 reliably transferring documents and goods to over 190 nations. One interesting sidelight.

USPS is definitely the cheapest way to ship to SVK from the US. The only other (better) option is fly on over and put it in your suitcase. :-) Pro Tip: do NOT put insurance on it from USPS or it will be flagged by Slovak Customs and could take weeks to clear (and likely they'll charge a customs & import tax).
