How else can I fund my Zero-Percent C of I to pay for security purchases?
You may debit, or make a purchase of a C of I, using your checking or savings account. This option is handy when you need to supplement the amount in your C of I for a security purchase. You may also route maturing securities, interest payments, or redemptions of savings bonds directly to your C of I. Your financial institution can even set up direct deposit from an annuity, pension fund, or other financial account.
