geez what are you shipping a bumper? *not my business just saying lol*
From here in south cali via USPS it'd be $120 under those exact terms

I imagine they're using something like UPS?
Though the calculator accepts it... are you sure it is ok to ship? https://www.usps.com/ship/can-you-ship-it-internationally.htm? they say the max length is 46 inches...
