The pink tax is when the same products are sold at higher prices to women and girls than men and boys. According to CBC's marketplace, at Shoppers Drug Mart, a 24-tablet pack of pain killer Naproxen respectively costs $6.99 and $7.49 for men and women respectively. When the matter was brought before Loblaws, the parent company of Shoppers' Drug Mart, they immediately announced that they would be changing the price to $6.99 for both men and women. Assuming the marginal cost is just $3 for this pain killer, did Loblaws make the right decision by changing its pricing strategy to a single price ?
