Re: Bought Arai on Ebay, insurance??
It's going to cost him more than $6.00 to ship the helmet to you, but maybe the seller is not experienced in shipping things. After shipping off more than a dozen Monster Parts over the last three months, I understand shipping costs much better. If it's less than a pound and not too big, it can go Priority Maiil for $3.85. Something heavy like front forks start to approach $30 for shipping. That helmet will likely cost between $10 and $15 to ship.
Of course, if you paid enough for it, losing a few bucks on shipping isn't a big deal. It's when you only charge $10 for something and it costs $14.85 to ship, as happened to me in one case, that it gets painful.
