I try to spend a set amount ($40) a month on emergency/disaster supplies each month. Because I can't afford to spend a lot of money at once, I've been taking the "ant's" approach to acquisition and storage of supplies. My goals for May:

• Purchase another ounce of silver (I buy an ounce every month to prepare for any complete financial collapse)
• Buy two more days of non-perishable meals (freeze-dried, canned goods, etc.)
• Complete my research on which non-hybrid seeds to store for TEOTWAWKI
• Buy 3 packs of non-hybrid seeds (probably include zucchini in the packs. If I remember correctly from my youth, I plant seemed to produce about 5,000 zucchinis)
• Puchase another pack of storm matches from REI and continue building my tinder kits.
