I started this project only for myself. I often make purchases in US internet shops, so I use mail forwarder services. Certainly, I don't want to pay much. And it had been quite tiresome for me to surf forwarders sites, estimate their rates every time I wanted to buy something. I think that you face such problems quite often too.
I am a programmer so I decided to make some instrument which would solve my shopping problems. And here it is - "Shipping calculator". Later I decided to share my project with others.
As I said before I'm just a programmer, not a designer, that's why my project may seem a bit clumsy to you. So if you liked the idea and can be of any help with my project, please contact me.
