The only thing I can add that'll be of max benefit to the majority is to counsel keeping yourself abreast of the latest developments. Remember - financial collapses don't happen literally overnight and the signs of impending catastrophy are hard to hide. A 36-48 hour head start on the sheeple will allow you to hit the warehouse stores (while your CC is still functional) and purchase bulk perishables. Critical items are rice, beans, flour, cooking oil, powdered milk, soup and drink mixes, spices, salt, and any bulk comfort foods like dried fruits and hard candies. These staples should already be part of your food storage preps; however, getting them at the last minute ensures freshness (oil and powdered milk spoil quickly) and delays the point where you will have to get into your long-term storage. Pay particular attention to ethnic foods - they're relatively cheaper and most Americans either overlook them (either never been hungry enough to eat unfamiliar foods or have prejudices detrimental to long term survival) or flat don't know how to prepare them. This suggestion is ONLY to augment an existing food reserve. The person who bases his survival plans on beating the last minute panic of a terrified populace might not survive the shopping trip.

ETA - Food is only part of a plan. If you haven't given thought as to how to prepare your "stash" for consumption, you might find yourself with wheat kernels or similar that are relatively inedible for lack of a grain grinder, etc. You should also give some thought as to how you will replace what you consume (gardening requires some skill that won't be gained overnight) and how you will preserve what you acquire fresh (for canning see gardening note!).
