Cost estimate for brake pad replacement??

My brake pad sensor went on a few weeks ago so I'm trying to get an idea on how much it's going to cost to replace them. Last time I paid $730 for new pads and rotors. Looking back at some past threads, I think I paid too much. Anyway, I'm going to be getting rid of the car next year so I need the lowest cost replacement. I'm assuming I won't be needing new rotors since the light just went on and probably on have about under 200 miles since the warning light went on. Can someone give me a rough idea on the cost? I don't have the tools or garage to do a DIY, so I'll have to take it to a mechanic. Last time they charged $240 for labor (brakes and rotor). Thanks.
