You can't be everything to everyone, as Hickory Farms found out. A company that started out with holiday gift baskets including sausage, ham, and cheese at one point had an offering of 2,500 different products, sprawling the company and resulting in a loss of favor with customers. Recognizing this issue, Hickory Farms streamlined itself, slashing their number of products from 2,500 to 300 with more modern visuals, descriptions, and other features, including less packaging and more recycled content. The company also overhauled their website, making it easier to shop online. All of this streamlining resulted in a price reduction of 13% that Hickory Farms was able to pass on to their customers. Brand strategist Jennifer Woodbery believes that this was a smart move, making the most of Hickory Farms' trusted name and image with an effective rebranding of offerings.
