Los Angeles based celebrity event planner Tony Schubert said: "It benefits the vendors, their goods and services to be shown to millions of people."
Among the free items the couple reportedly received for the wedding were the three Vera Wang dresses Kim wore during the ceremony and reception, worth $20,000 each, $400,000 in Perrier Jouet Champagne, and $10,000 worth of wedding invitations.
They were also said to have been gifted their 10 layer wedding cake from Hansen's Bakery - which at six feet tall towered over Kim - thought to be worth $15,000.
Kim and Kris are set to continue their wedding celebrations, with a second ceremony planned for New York early next week.
Despite all of the talk of money, the wedding day had many priceless touching moments, particularly the entrance of 21-month old ring bearer, Mason, the son of Kim's sister Kourtney.
Guest Kathie Lee Gifford said: "If it's possible to steal the thunder from Kim Kardashian Humphries, it was Mason. He was just the cutest thing. It just reminded me of the study in contrast.
"It was typically Kardashian, over-the-top, crazy, but ultimately it comes down to family."
