I picked up a giant Silva compass at a flea market earlier. I figure it was for orienteering training. After some google-fu, I found its usually in a $399 training kit full of compasses. It's basically for laying on an overhead projector.
I actually have use for it, aside from it being a odd collector's piece.
I did use coupons on baby food the other day...I got 50 jars of various baby food for less than $10. baby formula usually cost me $37 after taxes and I joined some baby group thingy that sent me a book of coupons..I get it for $15 now. they sent an est. 6 months worth of coupons.
