Charging fee for BGP prefix per /24?!

Hi, My recent inquiry to some network provider reveals that they are charging fee for per /24 announced. Obvious that would means they get to charge a lot with little to none efforts on their side. In a world we are charging total bytes transferred instead of bps on uplinks, i can't say I'm surprised that much. But does anyone else had same experience? Did you pay? Is this the new status quo now? Thanks.
