In all my years of working in bike shops as a younger man I never came across a tube with a hole in it. I did encounter a few with faulty Schraeder valves though. If you want to buy a bunch of tubes and store them for when you need them, be sure to store them in your wine cellar, stacked neatly with thin cedar wood planks between each tube.

Just kidding about the storage method but recently I did get a bad batch of tubes from a big box camping store. I had 5 tubes develop holes/leaks at the seams in different places on each tube. Changed to different tubes and the leaks stopped.
