An Easy Way to Save $1,378

"The basic principal is this – Choose a small dollar amount, like say $1 or $2 and put it into a jar or a savings account at the start of the week... Then next week (Week 2) double what you put into your savings account in week 1. So if you put $1 in your savings account in week 1, in week 2 you would put $2 into the account. Week 3 would continue in the same vein with $3 going into your account." - MonsterPiggyBank.com

PS: Starting with $2/week would net you $2,756! Without even accounting for interest...
