Because it has tracking and insurance? It's getting shipped properly, in it's original container, in a box with packing material, with a reasonable method of shipping. It's a quality product, so it's going to be sent properly and arrive in the new condition it was sent. I'm not going to take it out of it's box, tape it to a postcard, lie on customs forms, or anything else crazy. The post office tells me it's $20+ so that's what I forward to you guys. If you don't want to pay shipping, don't do it, I'm not twisting your arm. I'm not going to pay for the privilege of sending you an arrowhead though, when the entire point of this is a membership drive to support the forums and doing so negates the money brought in by the membership itself.
I don't think I'm being unreasonable here. I'm sorry that shipping costs more to Canada, the UK, or wherever, but that's out of my control.
Of course, it'll get tacked onto the end of your current subscription.
