One week before. Locate the large stock pot you’ll need for boiling the seafood and make sure all of your outdoor tables and chairs are clean and in good condition. Order your crabs in advance to avoid the holiday rush. Shrimp can be purchased in advance and frozen.

Shop. Divide your shopping list into two trips. One week before, shop for non-perishables, including napkins and paper plates and July 4th decorations, if you plan to use them. Three days before the holiday, shop for all other essentials and foods to ensure they won’t be sold out and to avoid the holiday rush.
