 You may find shipping complicated if you send items of various sizes and weights.

Flat-rate delivery solutions help address this concern by letting you fit as many mailpieces as possible in your chosen packaging up to a specific weight limit.

Here’s a breakdown of how a typical USPS Flat Rate shipping works:

  • Pick your packaging: Flat Rate options do not put a limit to the number of items you send. 

Still, you must use a container appropriate to the content. USPS offers multiple options for envelopes, weight limits, and shipping labels.

  • Prepare your package: Next, you put the content into the corresponding Flat Rate packaging. 

You can put as many items as your Flat Rate box (or envelope) can handle, provided the weight does not exceed the service’s imposed limits.

  • Pay the set fee: Flat Rate shipping charges you a predetermined fee regardless of your package’s size, weight, or destination. This fixed cost makes price calculations easier.
  • Wait for the package’s arrival:  Once you’ve securely packed your items and paid the fixed rate, complete the necessary steps. 

All that’s left is to wait for the shipment to arrive at its intended destination. 

Domestic Priority Mail Flat Rate shipping typically takes one to three business days.

USPS Flat Rates Are Awesome

USPS Flat Rate services are ideal mailing options for many as their price ranges remain the same regardless of what you’re shipping.

Shipping costs typically depend on the package’s weight when shipping anything through the post office. However, you can pay a flat shipping rate if your item fits a predetermined package.

With flat-rate services, your payment usually depends on the package type you choose, such as different sizes of boxes or envelopes.

For example, the shipping cost for First-Class Mail starts at $0.66 and increases depending on the item’s weight, shape, and size.

Media Mail, another USPS service for shipping media items like books, printed music, and recorded video tapes, charges extra if you include items in the package that the service does not allow. 

Flat-rate services can be convenient, especially if you cannot predict whether shipping by weight will cost less or more than your initial estimate. 

This option can also benefit you if you do not have a weighing scale at home to measure package weight.

 USPS flat-rate services may appeal to you if you’re a U.S. eCommerce merchant shipping domestically because they are often cheaper than weight-based rates.
