Query: unhappy and frustrated

this radio worked for about a month, until it was time to change the time for daylight savings. the "clock set" button malfunctioned, and since i paid cash for the radio and had no receipt, i called sony directly for help. can you imagine my shock when they said it would be $103 to REPAIR it? are they out of their minds? it's only a $40 item! can you say NEVER AGAIN???
