The purchase needs to be made before 31 July, and the cashback form must be filled and returned before 17 August. Maximum 3 per customer.
That makes rx4240 a nice small and cheap PDA — 2.8in LCD compare to many portrait-mode PDAs with 3.5+ inch LCD. Some hate it but I love the small size as it is really portable. Around $320 after the cashback, with 400Mhz Samsung CPU, Wifi, Bluetooth, SD slot and 64MB RAM.
