I use ASDA own brand foods I made the choice a month ago that I would live as I would live SHTF and only eat from tins. If it did not fit in one pan I would not cook it. Not only did I begin to feel more energy I even lost about a stone in weight. It made that much of a difference that I made the decision that I would live like this from now on. Therefore it does not matter if the sell by dates are shorter, or only a few years by using stock rotation I will always have 2 years worth of food once I am fully stocked up.
Dont get me wrong every now and then it is nice to have something different, but the bulk of my diet comes from one tin. Don't just pack the stuff away attampt to live as you would and see if it fits with your lifestyle. I know now if the snow continues to fall and I cannot get out does not matter I can always cook something to eat.
