While You're At The Marketplace has been which company's ad slogan?

“While You’re At The Marketplace” was an advertising slogan used by Winn-Dixie.

The campaign promoted Winn-Dixie’s Marketplace-format supermarkets as convenient one-stop shopping destinations. It ran prominently in the late 1990s, when the company was investing in larger stores that combined ordinary grocery departments with expanded general merchandise and services.

Winn-Dixie introduced its first Marketplace store in 1984 in Valdosta, Georgia. The format became an important part of the chain’s identity, and the phrase “While You’re at the Marketplace” was used across multiple advertising media to highlight the breadth of products available under one roof.

The slogan is easy to confuse with Winn-Dixie’s other long-running advertising lines. The company has also used “The Beef People,” “America’s Supermarket,” “The Real Deal,” and “It’s a Winn Win!” The clue refers specifically to the Marketplace campaign, not to the brand’s best-known meat-related slogan or its later corporate taglines.
