Cotton Balls mixed with vasoline - from the bathroom cabinet
Bicycle innertube cut into "Ranger Bands" - from the garage
Bicycle tube patch repair glue - from the local REI store
Candle stub - from the kitchen junk drawer
Trick magnesium birthday candles - from the local grocery store
Esbit fuel tablets - from the local army surplus store
Triox fuel bars - from the local army surplus store
WetFire (name?) waterproof tinder - from an NRA survival kit with a BlastMatch, StarFlash, and JetScream

Of these, only the cotton balls w/vasoline and the WetFire might be truely called tinder because they can catch a spark from a ferro rod. But the other things are similar to tinder in that they're the first things you might light with a match or BIC lighter, and then use to ignite larger things.
