Spending 4th of July week on the Cape with a friend and after having exhausted all our known eating spots, we stopped at Sam's at the last minute because it had come recommended by a friend. WOW! Aside from the fact that deli is stocked with everything you might need and they haven adjacent wine shop, they make the biggest and tastiest sandwiches I have ever had. It took me 2 sittings to finish mine. Expect a crowd. Expect a wait, but the line moves quickly. The wine section and the deli are independent so you have to pay separately - go prepared for that.
