I don't think buying food and stocking is a good idea if that's what you mean, the best way around this is to live below your means and add some other cash flows.
That's right. We have little experience in storing food and we don't have an appropriate equipment, so it is very likely that a big part of the food we want to preserve will go bad. The best strategy, in my opinion, is trying to find the places where we can buy cheaper food, and, of course, where we can earn some additional money.
