34. Store-Brand Products

Store-brand products line grocery shelves next to familiar names like Tide or Kellogg's, offering similar goods at lower prices. Their origins are obscure—made not by retailers but by obscure manufacturers revealed at trade shows like the Private Label Manufacturers Association (PLMA) gathering in Chicago, where companies pitch canned vegetables, oils, cosmetics, and gadgets to chains like Kroger and Costco.

Origins and Growth of Store Brands

Store brands, also called private labels, surged in the 1970s as "generics"—plain-packaged items like beans in yellow cans, marketed for skipping advertising costs. By the 1990s, retailers rebranded them under names like Trader Joe's, Kirkland (Costco), or Signature Select (Albertsons). Last year, U.S. sales hit $230 billion, comprising one in five shelf products amid rising prices. Shoppers value consistent discounts without hunting coupons; a box of Kellogg's might drop 20% on sale, but store brands stay cheaper ongoing.

Retailers gain loyalty and profits: gross margins run 30-35% on private labels versus 20-25% on national brands. Professor Kusum Lalawoi of Dartmouth's Tuck School explains retailers scan sales data to target high-volume national items for cheaper duplicates.
