I can't really think of one that does. Of course, quality is a real thing, so I will pick some better-know products over others, but in most cases, I just take the cheapest option. For example, I love generic brand soda, and the fact that it's almost always the cheapest option is a plus. I don't care to get Prairie Farms milk or Hershey's chocolate syrup or Sargento cheese, unless they're on sales good enough to warrant slightly-higher prices.
Like you said, it's probably happened. However, I just can't think of any instances. I don't need the world's softest, lotioniest tissues, so I wouldn't care about that. I guess the one instance where I take the known brand is with gaming peripherals. For example, I don't care to go Nyko for 360 batteries, though that's more about having all of the stuff the same than having a real brand PREFERENCE.
