Which of the following can be purchased with a debit card?

A debit card can be used to purchase money orders from the USPS. This option is correct because the USPS accepts debit card payments as a valid form of payment for money orders, making it a convenient choice for customers who prefer electronic payment methods.

In contrast, while a debit card can be used for various services, it is essential to note that not all postage services may allow debit card payments under specific circumstances, such as at certain kiosks or locations. For passport fees, the USPS generally requires payment via checks or money orders made out to the Department of State, rendering debit cards unsuitable for those transactions. Pre-cancelled stamps are typically sold for cash or by credit, which may not include debit card transactions in every situation.
