I was told that when the pull top cans leak its because they are ' close' to expiration date, or they are kept in a too warm environment. When buying can goods I will look for a close to or empty box on the shelves.Who knew we'd have to start treating can goods like eggs.I buy soda for company and I'm yet to get a 12 pk home.I keep a waxed produce box with an old towel in it to keep that sticky mess contained.
