Anyone have any secrets as far as shipping bumpers? The cheapest I can find for an XF bumper (wrapped in bubble wrap, plastic wrap, and then taped around is $184 via Fedex ... 72x19.5x22 ....

I paid $85 shipping when I bought it originally and just assumed that's around what it would cost when I send it... seller shipped via SmartPost, but I think that's only an option for business accounts.. any ideas?
