Phar-Mor (stylized as PHA℞-MOR) was a United States chain of discount drug stores, based in Youngstown, Ohio, and founded by Michael "Mickey" Monus and David Shapira in 1982.

[1][2][3][4] Phar-Mor's business model was based on selling a large quantity of merchandise with a very small profit margin.

Sam Walton once called Monus the only retailer that he feared, since he couldn't understand how Phar-Mor grew so rapidly in a short time.

Based on deceptive data and inventory, Phar-Mor borrowed millions, ostensibly to finance its unusually rapid growth.

Without Power Buying, Phar-Mor found itself directly competing with CVS and Walgreens, and lost out because of other chains' convenient locations.

Liquidation of Phar-Mor's inventory was handled by The Ozer Group of Needham, Massachusetts and Hilco Merchant Resources of Northbrook, Illinois.
