Walmart Wouldn't Fix a Flat

I've had great results with the tire plugs that are like a pipe cleaner covered with goo. I've put tens of thousands of miles on car tires after having plugged them myself with those.

I would use them in a pinch on my truck or trailer, just to get out of a bind. But even though I've seen them last for years, I would not want them on my TV or fiver and would get it properly patched.
