I recentley bought the LG Cookie KP500 phone.......HELP!!!!!!?

i fell asleep on the bus and when i awoke the LCD screen cracked, although the screen was smooth to touch. i cant read anything on the phone and when i took it to the shop they said the only thing i could do was pay 50 quid for a replacement. are there any web sites that sell cheaper screens or is there anything else ican do ????????!!!!!!!!!!! thanks!!!!!!!!!!!!!!!!
