You may have a problem there. You can stomp the cans down to save space.
I pick my mail up about 1 time a month, usually on the day before trash pickup. I have tried to bill the post office for the trash service, but it did not work. There was a time that I would open up the junk, and mail some of it back in the postage paid envelopes. Then they quit doing that.
Since I pay everything online, the mail box is almost 99 percent trash.
