Good deals on several BlackBerry models for $0.01 with service plans from major carriers, including Verizon, Sprint, AT&T, and T-Mobile.  In addition, you also get a $100 Amazon Gift Certificate.  Here is a screenshot for your reference.  As an example, a BlackBerry Curve with T-Mobile would normally have been $129.99 without the additional $100 Amazon Gift Certificate.  Assuming that you will use the $100 Amazon Gift Certificate at some point, that's a difference of $229.98 in cost.
