A personal equipment reserve kit consideration.

Good post NR, but I would opt for 300-500 rounds of ammunition as a bare minimum (MZBs do tend to reproduce rapidly)! $50 or £50 sounds a bit light too. $500 to $1,000 is more realistic. Pre-loaded bank cards may not work when the SHTF and cash is king. Fractional gold and silver coins may be worthwhile too (like for bribing your way past a roadblock).
