Hello, I just wanted to ask-I am developing a board and it will soon be finished. When I click the shopping card icon, it shows an estimate of the price-but this estimate doesn't change with the quantity I select! I originally thought it's a price per one PCB, but when I increased the size, changing the quantity resulted in the change of price. So-can you please confirm whether the price is for batch or for single PCB? Also, don't really feel like hitting the purchase button without knowing anything about the shipping costs! Could you please give me an estimate of the shipping fees to Czech Republic for a $21 board? Also-just out of curiosity-why is it more expensive if I check the "open hw" checkbox? Sorry if these questions have been answered already, I couldn't find it anywhere. Thegoodhen
