Gross domestic product (GDP) is the monetary value of all the finished goods and services produced within a country's borders in a specific time period.
Recent survey findings from RetailMeNot show that this season's wedding guests plan to spend $195 on a sibling's wedding gift, $159 on a best friend, $63 on a coworker and $45 on an acquaintance. Yet other sources say somewhere in the ballpark of $75-100 for a coworker, and $100-125 for a friend is appropriate.
The average amount spent on gifts this year will be about $109 per wedding, but nearly twice that if the bride or groom is a close family member. And, of course, it's not just guests that are dropping serious cash on the Big Day. According to The Knot's 2013 Real Weddings report, marrying couples are now shelling out $30,000 on average for their weddings and spending an average of $220 per guest.
