3. As the arrangements are generally complicated, there are plenty of services that can be hired to help with the planning and execution of the ceremony. There is also an amazing amount of free advice covering every aspect of the wedding: planning the photographs, selecting the wedding rings, choosing the flowers, picking the honeymoon spot, and so on. One magazine lists over 350 such pamphlets that can be had for the asking, published of course by businesses who have something to offer. Considering that weddings do more than 12 billion dollars worth of business annually in the U.S. alone, such activity isn't surprising.
4. What is surprising, is that no one company dominates the industry. It seems that when people plan for a day as special to them as a wedding, they resist standardization. They turn instead to the small local suppliers known to them or to their friends. Family members or friends often serve as photographers, caterers and musicians. This not only helps bring the wedding cost down, it makes it more personal. What about the couple that doesn't want to take part in this billion dollar industry? They can go to city hall and get married for less than the price of a hamburger.

1. Though the odds may be barely in their favor, every couple who goes to the altar believes that they will make that trip only once in their lives. They want the day to be perfect, and they are asking for much more than good weather. They want the most beautiful clothes, the freshest flowers, the prettiest music, and the best food. No one, especially not the bride — nor her family who will foot the bill — is in any mood to economize.
2. A quick look at any bride magazine will reveal that plenty of attractive goods and services compete for a share of the wedding budget. Beside the obvious choices of rings, dresses, flowers, and photographs, there are the less apparent expenses: a lavish cake, a rehearsal dinner, a reception, music for both the ceremony and the reception, tips, and even napkins and matchbooks printed with the couple's names and the wedding date.
