When I shipped mine out in September, I think it was under 8 bucks, around 7.80. If the prices have gone up, then I would still think its under 10 dollars, or 15 if you do a flat rate small box. I was really surprised at how cheap it was for international shipping. But all of this was with an impression kit I did myself, and it included a return shipping box, which made it cheaper.
Thanks, that actually sounds really cheap. I thought it'd be more than that too.
