You can also use a local company called Junkster out of the north shore. They sell bags at Tags.

Something to keep in mind about these bags is that they need to be able to get to the bag off the side of the truck. Not the back of the truck. Putting it down deep in a driveway is not an option, they will not be able to get to it. I tore out the flooring and piled it outside. Then scheduled the pickup. The morning they were coming, I transferred all the flooring into the bag at the curb so the truck could easily pick it up.
