The Church of Jesus Christ of Latter-day Saints' Provident Living Website has a form for ordering food from the Church's Home Storage Centers. Generally, the centers are located in areas with a larger concentration of the Church's members. If you are interested in visiting a center, you can contact a member of the Church and ask them to accompany you to a local center.
Although you may not be located near to a Home Storage Center, the form itself provides a way to compare prices and to see what foods can safely be stored for extended periods of time. The Provident Living Website also provides valuable help in all areas of preparedness, not just food storage.
The members of the Church believe that a cardinal principle of the gospel is to prepare for the day of scarcity. Work, industry, frugality are part of the royal order of life. Remember these words from Paul: “If any provide not for his own, and specially for those of his own house, he hath denied the faith, and is worse than an infidel.” (As quoted from Keith B. McMullin, “Lay Up in Store,” Ensign, May 2007, 51–53)
