If the Office Uses Stamps for Mailings, What Is the Most

If the office uses stamps for mailings, what is the most efficient way to calculate postage?

A) Weigh items on a postal scale and then look up postage at the USPS Web site.
B) Use an online mailing service, because it is not necessary to weigh items for mailing.
C) Place one first-class stamp on letters of two pages or less and bring other items to the post office.
D) Place two first-class stamps on all letters, and set packages aside for a weekly trip to the post office.
