Kansas City Steak Co.
What started in 1932 as a family-owned butcher shop in Kansas City has expanded into a website that still gets its beef from local stockyards. Steaks are aged 28 days then frozen for shipping, and most cuts are also available in prime. [Filet mignon starts at $2.13 per ounce direct from kansascitysteaks.com; we found comparable (and some better) deals on the same KC Steaks products at Amazon.]
What else you can get: Wagyu beef filet mignon, a domestically raised breed of Japanese cattle with better marbling and more flavor.
