Popcornopolis Zebra Popcorn

Your holiday party guests expect something more than just plain popcorn. Serve a snack that stands out and stock your kitchen with this sweet (and subtly salty) caramel and white/dark chocolate treat.

A few words of caution … Costco Reddit user Salty_Drawing4076 warned other shoppers, "Very good but extremely addicting. Might eat the whole bag in one sitting."

Price: $4.99

Serving shrimp at your holiday party? If you answered yes, don't forget the cocktail sauce.

At $4.99 for over two pounds, this extra-spicy horseradish-infused blend is a bargain bulk buy. Target sells a 12-ounce bottle of Heinz for $3.39. In a price-per-ounce showdown, Costco wins at $0.15, compared with $0.28.
