I want to purchase a Genuino 101 from Bangladesh. How much extra cost will I have to pay and how will I receive the product?
Sorry, but this Forum is not connected with the Arduino store. It is just for assisting people with programming Arduinos.
I'm not sure how you can find an aswer to your question.
But once you get it, don't forget we are here to help get it working.
All we ask is that you try to work it out yourself and read all the help available on this site.
You don't have to buy an Arduino 101 from the Arduino website. They are also available from other suppliers such as Sparkfun. Maybe there are suppliers in your own country.
