Amazon sent an email out last year allowing you to select the option of receiving digital forms. You can now select that option during the tax interview. Though I'm going to assume it's too late for the 2015 tax season.
Blue and white water. The Nile is the longest river in the world, with many different stretches which flow through a number of east African countries. In Sudan, the Blue Nile and White Nile meet at Khartoum, from where the river is called the Nile as it continues north into Egypt. As the Blue and White Niles meet, you can clearly see the waters of the rivers joining together by the difference in their colour.
Shorter than the White Nile, the Blue Nile starts in the highlands of Ethiopia and Eritrea, picking up black sediment en route to Khartoum. The Blue Nile is fed by monsoon rains, and when rains are abundant, the Blue Nile can actually flow backward near its confluence with the White Nile.
