Where can I pay to throw away extra bags of trash?

I live with my parents currently and I’ve been cleaning heavily the past few days. The thing is I don’t want to fill up our trash cans to the point they can’t throw away their trash as well. I also don’t want to be the type of scumbag that throws their trash bags in random lots.

If anyone knows of a place, please comment and give an average of how much it cost?
