Collecting cans can make some money but it certainly is not gonna make you a lot of money or get you rich.
I collect cans when I see them and then save them up for a year and take a pickup bed load full of bagged cans which brings me $150.00
So it's not much but it gets the cans recycled and helps pay for my vehicle registration renewal each year but I don't collect cans as a job just only when I'm out walking or riding my bicycle anyway.
