A pager is a wireless telecommunications device that receives and displays numeric or text messages, or receives and announces voice messages. One-way pagers can only receive messages, while response pagers and two-way pagers can also acknowledge, reply to, and originate messages using an internal transmitter.
Other Shipping Options. If you choose to ship via Priority Mail in something other than flat rate packaging, youâll pay a rate based on the weight of the package and the zone you are shipping to. You can use your own packaging or USPS non-flat-rate packaging, but the packages must be clearly marked as Priority Mail.
Priority Mail. The U.S. Postal Service has multiple delivery options available for using the Priority Mail service. You can mail items -- that meet certain size specifications -- for delivery in one, two or three days. The service comes with free envelopes or boxes and labels and up to $50 insurance without any extra costs.
