Thanks, agnut. Well-written, sound advice. I didn't participate in the Bartering and Horsetrading thread at GIM, but I look forward to following along this time, and I am grateful for the opportunity.
I visited a drugstore (CVS) yesterday and noticed they have a green sticker for items that are 75% off. I bought a handful of nail/toenail clippers for about 47 cents each, and they are going into storage for bartering when TSHTF.
