For garbage
cans (
rubbish bins): Take a few extra liners to the can when you're replacing the old liner. Just fold them on the bottom, and replace the new one like you would. If you put, say, five, under the new one, you don't have to run to the place where you store your liners five times. Just pull out the full liner, tie it up, place it on the floor, and grab one from the can. Saves steps.
