Consumers can choose to purchase more or less varied product assortments. The present research demonstrates that the payment method used for purchase affects the variety of options selected. Using a mix of secondary data analysis and lab experiments, we show that payment methods that elicit a higher pain of payment, such as cash, decrease variety seeking. We also elucidate the process underlying this choice outcome: as the pain of payment increases, consumers experience a higher need to justify choice, increasing the share of options that are easier to justify (e.g., one’s favorites). Our findings offer a useful tool for managers to influence the composition of multi-item purchases and for policymakers to affect well-being via variety seeking.
