rtcvb32: If you don't consider things new and will shop around a little, used book stores you can get a book for $1, although those are probably children's books.
Second hand stores, a decent knife, 10+ feet of cord/line, a shirt, a few handkerchiefs maybe.
If we're talking food management over time for $1/day then that is a bad way to judge it. I can get a bag of potatoes and other veggies that add up to $10 or so but I can make a meal a day for over a week, just takes a little more time.
Flea markets will have items for cheap as well, so there's no reason to have real low quality dollar store items.
There's always one sensible mature person here to take the fun out of a thread. :P
