A wonderful idea to save painlessly -- and have $1,378 at the end of each year. For the first half year, you are saving less than $100/month; then for the next few months, up to (finally) $250/month.
Put aside the amount of each week into a savings account. Don't spend it until the end of the year, or continue to save into the next year for a larger amount.
If you have discretionary funds available, you can do the same for an IRA or other retirement or education savings. The trick is to simply do it, and allow it to grow. Makes so much more sense than spending funds ahead of saving them, on a credit card for example, and then incurring fees of various kinds.
