What could be luckier than getting married on the seventh day of the seventh month of the seventh year? How about having that July 7, 2007 wedding at your local Wal-Mart?

The world’s largest retailer on Tuesday announced a contest where seven couples will win a wedding and reception at a Wal-Mart lawn and a garden center.

The contest, sponsored by Wal-Mart and G Squared is in connection with something called “Proposal Day.”

Winners will receive a wedding package with an estimated value of more than $5,000, which includes a cake, food, 14-karat gold and diamond wedding bands, floral bouquets, digital cameras, a $1,000 Wal-Mart gift card and more.

But it is also an essay test. The application asks contests to answer the question “Why is this wedding ceremony and reception location of interest to you?”

The winning couples won’t be the first to get married at Wal-Mart.

“Local lawn and garden areas have provided a vibrant backdrop for a variety of ‘I do’s’ over the years for those who have ‘found love’ at Wal-Mart,” the retailer said in a press release.
