What makes you say, "We've got to go to the store?"

Yesterday we ran out of Saran wrap, and I realized that there are certain items that make me say, "We've got to go to the store." when we run out. Saran wrap is one of them. The other I thought of was coffee. My friend Britni also added laundry detergent, which I agree with.

• Saran wrap
• coffee
• laundry detergent

I'm curious what are other people's "essentials"?
