Rao's Homemade Marinara sauce has become a fan favorite at retail stores, but Costco offers the best deal with two 28-ounce jars for about $11.79.

On Rao's website, one 24-ounce jar of the Homemade Marinara Sauce costs $8.99, but at Costco, a 28-ounce jar costs about $5.89. One TikToker bought two jars on sale for $8.69.

Rao's Instagram channel captioned a photo of two Costco jars, "Pasta lovers, rejoice! Stock up on Rao's Homemade Marinara at Costco and never run out again."

In 1896, Rao's, a Southern Italian restaurant, opened in Harlem, New York. The restaurant serves top-tier, celebrity clientele with only 10 tables.

Frank Pellegrino Sr., who began working at Rao's in 1975, got tired of saying no to people who wanted a reservation and introduced the sauce for retail purchase in 1992.

One Redditor wrote about the sauce, "It's incredibly well-balanced, it has an outrageous aroma, and it's packed with meatiness and concentrated tomato flavor."
