Dollar Store Survival Gear Shopping for SHTF bug out bag

http://www.thedoityourselfworld.com Got some dollar store survival gear to add to my shtf bug out bag. I am on a mission to prove that you can put together a complete bug out bag from dollar store items. You will need to visit various dollar store types to get a good variety of items. I have been to three separate dollar stores and now have a pretty good survival bag put together (watch for video). I am just looking for a few more important items. The bug out bag I am making right now will be a vehicle bug out bag. Hopefully this one will get me to my main survival gear or a shelter. It should keep a person alive for 3-5 days, enough to get to shelter. In the Army I could march about 20 miles per day. The city, which is the farthest I usually go from home is about 80 miles away. That puts me at 4-5 days from home at the worst on a hard march. One of the most important items cannot be found in any dollar store though. That would be a good water filter. Everyone should have the ability to filter water on the run if needed. Iodine tablets can be used in a pinch if you pre-filter the water first using coffee filters to get the junk out.
