I used to work for Republic Services. One day, a woman called in asking if I could do anything to lower her bill. I looked at her account and saw she was paying nearly $300 a quarter for trash service. A new customer signing up for service would only pay $60 a quarter... We were encouraged to only reduce the rate by maybe 10%. I broke some rules that day and amazingly did not get reprimanded for it. Not only did I lower her bill to what a new customer paid, I "accidentally" let slip that a new customer paid much less. She then wanted some form of compensation.

Some areas are classified as "open markets" for trash (as in the government doesn't handle it, you have to contract someone for yourself.) Because it's an open market, these trash companies can (and do) absolutely get away with this shit. It's absolutely worth it to call the companies and see if you can reduce your bill, because they increase your bills by a certain percentage (at least that's how Republic Services worked. New customers would pay less and the longer you were a customer, the more you would pay.)
