Yeah, I see a number of the same items at my local dollar store. Some of the things are a great deal for a $buck like the glow sticks and mylar blanket. Small FAKs are OK for the extra supplies but I wouldn't rely on them without some beefing up. A few cheaply made bandaids are OK for minor cuts but that's about it.

But for me cheap waterproof matches or a knife really aren't worth it. These are critical items IMHO. Getting the el cheapo ones is better than having nothing at all but good stuff can be had for not much more. For example a good fixed blade (Mora) is only $10-12.
