Omaha Steaks offers its Omaha Steaks Prime Rib Menu for $89.99 plus $19.99 for shipping. That's tied with last week's mention, $82 off list, and the lowest price we could find. It includes four 8 oz. precooked prime rib slices, two 12-oz. roasted garlic mashed potatoes trays, two 6.5-oz. green beans trays, and one 6.5-oz. gourmet horseradish sauce jar.
