So you believe every Amazon customer should get in the promotion of X amount of free service for a whole year without any retention mechanism? In comparison if you ask your internet provider to bump you up from 1mbps to 2mbps (or to lower the price from 50 bucks to 40) because they have a promotion for new users, and they give it to you, providing you sign a contract for another 12 months, is not equivalent to telling the internet provider that because they are offering a free year of service (up to lets say 5 gigs of downstream bandwidth) to new customers you should do to and without a contract specifying that you're staying with the company afterwards.
