Another way to save is to be flexible about timing. Saturday evening weddings tend to be the most expensive, Dena Davey said, since they usually involve a dinner reception and event spaces often charge more for that time.
"Fridays and Sundays are really popular right now," added Davey.
June and December are the most popular months for weddings, so vendors may be more willing to negotiate if you are talking to them at other times of the year.
Time of day can make a big difference too. A buffet lunch is less expensive to provide than a sit-down dinner—and appetizers and champagne in the afternoon cost even less.
