Traveling extensively for work has allowed me to build up a great supply of toiletries. Not only for personal use, but in a SHTF scenario they will make for great barter items. Most hotels replace the items every day. So a three day trip can yield a pretty good stash. My wife used to make fun of me, until someone we know had an emergency, we were able to put a kit together for them that carried them for a couple of weeks. She is now a believer.
