I found site "sparkfun.com" and that they can ship boards into Ukraine.
Before you go ordering, I would definitely look around some more, especially to see if maybe there are any closer options; surely some place like Seeedstudio (or another Chinese supplier?) could ship you one?
Don't get me wrong, I like Sparkfun - but they are a little closer to me than you (I live in Arizona, USA), and I still find their prices a little high, but reasonable for a US distributor. You would not only be paying that premium, but the extra expense of shipping...
Good luck with your search!
