Did you know you can buy beer in West Virginia and NOT pay a deposit back on it, and then bring the empty cans back to New York State to get paid 5 cents per can. Unlike Pennsylvania beverage containers, West Virginia beverage containers have NY State-compatible reverse bar codes on them, and are accepted at retailers that sell that brand of beer.
This of course is illegal, but impossible to prove, because the reverse bar codes are a standard feature in many states.
