What service is offered by the USPS for printing postage online?

The correct answer is Click and Ship because it is the service provided by the United States Postal Service (USPS) that allows customers to print postage for their packages directly from home or their office. By using Click and Ship, users can select various shipping options, pay for their postage online, and then print the shipping label, making the shipping process more convenient and efficient.

Other services mentioned may have similar functions, but they are either not officially recognized by USPS or do not specifically offer the online printing of postage that Click and Ship does. Click and Ship integrates with other USPS features, ensuring a streamlined experience for customers who wish to manage their shipping needs without visiting a post office. This service is particularly beneficial for businesses and individuals who frequently ship items and prefer to do so from their own location.
