I agree on the importance of weapons, but they're lower on my list of priorities for a good reason. The part of a zombie apocalypse, or societal collapse that I would most wish to avoid would be the initial chaos. Police would be shooting people, fighting would break out over resources, disease and infections spread easily(if they are a factor and a person can't rule them out). The cop station would be chaotic and defended. Gun shop owners would be defending their shops. It seems that the easiest time to get killed or badly wounded is in that initial collapse of reason and order. So, I'd stay alive by hiding out for that part, hit a smaller town shop for resources if needed. After things settled down a bit, I'd go hunt firearms. They're much easier to get from the dead than from the living.
