When you buy a bottled beverage in California you pay an extra tax called the CRV or California Redemption Value. This tax is actually refunded to you if you recycle the empty container, which is a good thing as it encourages folks to recycle. The loophole in the system is that manufacturers are somewhat lazy and bottles of soda bought in other states frequently still have the CRV code on the side. If you were to go to Arizona and buy a truckload of empty soda cans your could theoretically make tons of money at the expense of California taxpayers. If you do this you are an asshole and I hope you get caught like these bastards did after making over $6 million.
