I read about it all the time. Get extra for barter. Almost to the point of hoarding something that you use but you can also use it as something to trade. I was thinking about it today. I keep reading that I should have extra seeds and bullets so I can trade them for something I need. While I agree that I need to stock up on what I use and may need, and get extras to share, I don't quite agree with the theory of getting as much of certain items as I can get my hands on so I can barter for something else.
I will try to have extra. In fact, my motto is that unless you have enough for your expected lifetime (or the lifetime of the product) then whatever you're collecting isn't too much. But do I really want to get two or three lifetimes worth of seeds, bullets, or whatever so I can trade? Wouldn't I be better off spending my money and effort getting enough of what I need?
Sure you should plan on having extra to be able to give away to family or friend that runs a little short on something but do you really need to start stocking up on the extras before you stock up on your own basic needs?
The kids were good today so they got to go to the football game. We even went out to dinner! Taco Bell. Five items, two for each of them and one for me. Came to a grand total of $5.25. They were very excited about being taken out to fast food. Normally the only time they eat something not home prepared is when we travel, and even then we usually bring our own food. Driving less than an hour to attend a football game doesn't constitute out of town travel so they thought it was extra special.
