Coogie Johnson rides up to the corner store to get a grape pop and beef jerky. Habib, the store owner, tells him it’s $1.00 for the soda and $1.75 for the jerky. Coogie then tries to talk Habib down to letting him pay $0.25 for soda and pay full price for the jerky to which his son nodded in approval. Even though the retail price for the soda and the jerky are $1.00 and $1.75, respectively. Coogie knows that the soda is priced well above the marginal cost and attempts to negotiate the price down closer to the marginal cost. Habib argues that it’s not fair to charge him a different price than other customers, but the son recognizes that some profit is better than no profit and agrees to sell it to Coogie at a lower price.
