Dining out is one of life’s simple pleasures, especially in retirement when there’s more time to meet friends, enjoy family dinners, or skip cooking after a busy day. But restaurant meals can quickly become one of the biggest discretionary expenses in a monthly budget. AARP says that members who spend about $60 per week eating out could save up to $450 per year by taking advantage of member dining discounts. Is that math realistic? The answer depends on where you eat, how often you dine out, and whether you consistently use the discounts available through your membership.
