Conditional $250 Discount
The Price listed above for this phone includes an instant $250 discount from Amazon.com. You agree to repay this $250 discount to Amazon.com if during the six-month period following activation you: (1) fail to pay your balance due each month on time; (2) fail to maintain your account in good standing; (3) disconnect the line of service; (4) transfer the phone to another line of service; (5) decrease the value of your service rate plan, including canceling or removing required PDA, BlackBerry, or smartphone features after your product has shipped; or (6) use this line of service to replace an existing account with the carrier. The discount is available only if you are activating a new, non-substitute line of service. If you do not follow these rules, you authorize Amazon.com to charge your credit card $250 as reimbursement of the discount without need for further approval. Third-party resellers are prohibited from purchasing cell phones on behalf of customers. **Purchase limit five (5) cell phones per household.**
In short you can't buy the phone at the low rate and cancel the 2 year agreement or you will be charged the cancellation fee and the addition $250 that Amazon.com is giving you.
