Can you add other shipping options for shipping to the US?
For 1 or 2 boards, the online store tells me that the cheapest shipping option, UPS Saver, is 55.99EUR.
The datasheet shows the "Condition on delivery" as with some pins soldered on. If you leave off those pins, could they be shipped more economically in an envelope instead of in a package?
I'ts not my shop, and I'm glad that I don't need to do all the shipping work but I've contacted the shop owner and he says, they'll ship it cheaper on request, if it fits in a envelope (should be possible with 2 boards). It is more work for them, so it is not a standard shipping option, but you can use the contact form on their website to ask for. The advantage of UPS is that you get it in 2 days, less expensive shipping methods may need up to 2 weeks.
