Earlier this week my wife changed our trash pickup service companies. We'll end up saving significantly over the the 3 month billing cycle. Our last bill was for a little over $105 for the next 3 months of trash pickup twice a week. With the new company we'll be paying around $63 for 3 months of service but pickup is only once per week. We don't normally accumulate enough trash to justify twice a week pickup so it was nice that she found a way for us to save on our trash. It isn't a huge savings but we'll end up keeping around $170 more over the course of the year.
It's good for everyone to take a look at your bills, especially recurring ones to determine whether you're getting full use out of them. In this case it would be just as easy to just stockpile our trash since we don't have full pickups anyways and save by only getting one pickup per week.
