Don't toss the spare change
At six-month intervals, find a coin sorter and deposit your change in a savings account. (One MONEY staffer's family saved $1,000 in stray coins last year.)
Take advantage of the concierge
Book a room on the hotel's concierge floor. It'll cost $20 to $40 more than the same digs on another floor, but consider the freebies: drinks, hors d'oeuvres, dry cleaning, shoe shining and help with reservations.
Start your kids saving early
Have your child open an IRA. Kids who earn money from an afterschool or summer job can put as much as $4,000 a year into a Roth IRA. After five years of tax-free growth, he or she can make penalty-free withdrawals for college -- or get a jump on retirement.
