The ketchup has a big following. Many people we spoke with say it's just plain addictive. Whataburger, which is headquartered in San Antonio, made a partnership deal with H-E-B earlier this year to put its ketchup up for sale, along with the original mustard.
While you can still pick up the packets for free with your order at whataburger, the ketchup sells for just over $2 at the store.
