@black03 - nice generalization....but wrong. Many believe. I for one.
I Permanently fix my flats with Black Jack, not temporarily.
Canadian Tire sells the equivalent kit for about $15. Not same quality of tools, but does the same job for light use in an emergency.
A tire pump compressor for another $15.
Total $30 for a permanent repair kit that will do dozens of tires.
And a large plastic garbage bag to sit on the ground, about 50 cents.
Permanent repair, with no tire shop yahoos monkeying with your runflats and wheels.( granted, I have a great tire shop that will not mess up runflats about 50km away). Use them for new tires only.
I have a special car that you can not get runflats for, but that has no spare.
It does however come with a phone number for a tow truck, and the only place that should touch it is dealers that are during some drives, 2000km away.
I learned what works and what does not.
