Every couDle who goes to the altar(圣坛)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．Thev want the most beautiful clothes，the freshest flowers．Moreover，her family who will foot the bill is not in any mood,to economize．
A quick look at any bride magazine will reveal that plenty of attractive goods and services compete for a share of the wedding budget．Besides the obvious choices of rings，dresses，flowers，and photographs，there are the less apparent expenses：a lavish(奢侈的)cake，a rehearsal dinner，a reception，music fbr both the ceremony and the reception，tips，and even nadkins and matchbooks printed with the couple’s names and the wedding date．
As the arrangements are generally complicated，there are plenty of services that can be hired to helD with the planning and execution of the 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 published，of course，by businesses who have something to offer．Considering that weddings do more than l 2 billion dollars worth of business annually in the US alone，such activity isn’t surprising．
What is surprising is that not one company dominates the industry．It seems that when people plan for a day as special to them as a weddin9，they resist standardization．They turn instead to the small local suppliers known to them or to their friends．Family members or friends often servee as Dhotographers，caterers and musicians．This．not only helps bring the wedding cost down，but makes it more personal．
