Amazon Wireless discounts the HTC EVO 3D to $149.99
The price nets you an HTC EVO 3D and a two-year contract with Sprint, which afterwards becomes month-to-month. A $200 Early Termination Fee applies if you cancel after the 30-day test period, and before the fifth month of service. After that the ETF is lowered with $10 each month, until it hits the minimum of $50 twenty or so months into your contract.
