> you only get your money back when you return the cans and bottles you bought and paid for
Correct. We pay price+deposit, get deposit back. It is break-even to us (minus the float of a dime for a month).
> Good laws for sure, but you are not making money on the cans and bottles unless you take in cans and bottles that you did not purchase
Which has interesting side-effects.
General Assistance (welfare) lets you buy food for the children, but not cigarettes or beer. You can buy bottled water, very legitimately (much Maine well water is dubious or bad). You can buy a 96-pack of small bottles of water, welfare covers the deposit, dump the water and go back to get the deposit refund. If you dump the water in the parking lot, someone will notice and call the cops. It's not clearly illegal, but you could lose your welfare.
NH has no bottle law. There are Maine towns along the NH border where can refunding exceeds the cans sold. Clearly someone smuggles NH cans (no deposit collected) into Maine (deposit "refunded"). This is illegal, but the State has no skin in the game so hardly cares. The drink distributors don't like getting ripped-off, but there's dozens of small roads over the border so is impractical to watch for pickups full of bags of cans. _OTOH_: NH has low-low tax on booze, and their big liquor shop is a mile outside of Maine. Lots of Mainers get their booze in NH and smuggle it back. This directly hurts Maine government (lost tax). Maine complains, NH laughs. In *that* case, the main road into the big NH booze shop is the TurnPike, and Maine occasionally watches the northbound tollbooths for cars overflowing with cartons of Seagrams. This is for show; they can't possibly catch 1% of the booty.
As Shooter says, homeless cans don't stay homeless, especially at 5 or 10 cents each. Poor folk (we say "thrifty") keep a bucket for deposit bottles, and run them back when it fills. Rich folks can donate to scouts or schools who collect the refunds. Reckless folks throw cans out the truck window, and I make a nickle a week just walking the ditch. We find enough roadside cans on our travels that we have a pail in the minivan; sometimes you find the remains of a parking-lot party and score a buck in one swoop. Quite a few folks collect cans/bottles as a steady income ("take in cans and bottles that you did not purchase"), walking the roads and parking lots.
I said it is break-even. Actually the recycling agents get a cut somewhere. It must be a slim cut, many quit the business. A lot of time and a lot of storage (apparently they don't crush). There are independent recyclers, some long-time and others come and go. Some stores take-back, but here it is not required. Wal-Mart did for a year and one day the machines vanished. Shaw's supermarket has nice machines (they scan the can and issue a credit slip); Carrol's minimart has a guy in the back, but most stores don't.
Main difference is: with bottle law the refund tracks back to the beverage distributor, so the bar-code must be readable. With no deposit, you get the bulk scrap price, and nobody cares who sold it, only that you are not mixing steel and dirt in with aluminum; you crush.
40 cents is a good price. I remember 20.
