I respectfully disagree with CANOEDOGS. There are some very good items at the dollar stores/ Yesterday I purchased a very nice aluminum nano flashlight, the lanyard portion of which I will be grinding off to save space in a PSK. I also bought some packets of glow sticks. At four sticks for a dollar they gave off a surprising amount of light. I tested one last night about 8:30 PM and it was still going strong at 5 AM. There are also medications, first aid supplies etc. I notice they even have Clif bars. And oven bags which is my choice for water bags in PSK's, at four for a buck as opposed to the only slightly heavies and five times more expensive Reynolds bags. JMHO.
