lol!! I really laughing about you!!!
You say you need to pay "only" one third in taxes!
I am in Brazil. If I buy things that cost more than 50 USD, I will need to pay 60% in taxes! Yes, more than it, EVERYTHING have a overprice of 60% (the price is the sum of products + mail than you apply this taxes ). And, if I use DHL or Fedex, there are more 17% in taxes! Sometimes, there are more "surprises things"to pay!
Welcome to Brazil! You just need pay about 30%! Not a big deal!!!! :'( :'(
But sometimes, if I have lucky, I don't need pay anything more! But it is rare! And I need to buy uncommon things (and hardware like this rfduino is one), from some countries (China is not one of then) and use the most slow way to send!
