Weddings are big business in the United States. The average cost of a wedding in America is $20,000. This price covers the reception hall, the catering, the dress, the cake, the flowers and other decorations, and a slew of other expenses. The cost of a wedding could be substantially lower if one were to opt for a basic walk down the aisle, or substantially more if an exotic locale or a whole weekend of activity is desired. A kosher wedding is usually double the cost.
