Mmmm, well you better put that info up on your website else you're going to loose a lot of (international) business.
I think even the price for shipping it within the USA is way too high. Let's face it, an aluminium knob like that weighs close to nothing and is tiny. You can easily send it in a bubble envelope through regular USPS mail. I bet shipping it to Europe would then cost less than $15,-, priority airmail.
I've ordered several things in the US (last thing was 2 Suzo Inductive joysticks + a pinball knocker, so a lot heavier and in a box. The postage for that was around $17,-
It's amazing that USPS can still handle these prices considering "the high price of gas in today's world"......come'on Dave, you don't believe that stuff yourself do you ? Yes that could be a couple of cents more, not 10's of dollars....
David, your spinner looks like a great quality product, I'm not critizing you or your product, I'd just think you'd get more business if you could offer alternatives to the default shipping. As you indicate you do, but don't forget people could very easily be turned off by the high shipping quotes from UPS.
