I remember when I first started reading the ETS site that some of the higher quality Survival Kits that Doug reviewed would replace the first aid and water purfication parts when they expired.

In the survival kits that I build with kids as part of a one day basic survival course, I have them include my business card in the kit. It gives them something to write on, use as fire starter and I promised to replace their kit if I can use their survival story as a real-life example in my course. I have been doing this for 4 years but have not yet had a kit used in a survival situation to my knowledge.

I forgot to add that this is a free course and the kits are also provided at no cost. The program is sponsored by government, business or personal funding.
