Amazon Associate how to make simple text link

If you would like to link directly to an item's page using a simple link, do this

http://www.amazon.com/dp/ASIN/?tag="tracking ID here"

Replace "ASIN" with the 10-digit ISBN or ASIN of the product,

So from this link  http://www.amazon.com/Incredibad-CD-DVD-Lonely-Island/dp/B001NY4WLA

You need "B001NY4WLA"
