When budgeting funds for each person's gift, remember to factor in the cost of wrapping paper or gift bags. These decorative elements can add big bucks to your holiday expenditures. Better yet, pass on the expense altogether by taking advantage of our favorite word of the season: free. As an incentive, many stores offer free gift-wrap. Others allow charities to wrap gifts for donations -- often for less than it would cost you to buy wrapping paper, tape and bows.
