Carrier Guides
What's the Cheapest Way to Ship with USPS in 2025?
The USPS is one of the most well known carriers, offering many domestic and international service. This guide shows you how to find the cheapest options.
USPS Ground Advantage is the cheapest option for most eCommerce shipments. It handles packages up to 70 lbs, delivers in 2–5 days, and costs less than Priority Mail or Express.
Of course, the lowest rate still depends on weight, size, and destination. Easyship’s USPS shipping calculator makes it simple to compare all services with discounted CPP pricing — cheaper than the post office — so you always find the best value.
In this guide, we’ll outline USPS domestic and international services, what drives your shipping rates, and how to secure the lowest costs.
Finding the Cheapest Way to Ship USPS
As you would expect, there is no one-size-fits-all cost when determining USPS's cheapest shipping, as this depends on several factors. These include:
- Custom packaging: Sometimes, using your own custom packaging results in the cheapest way to ship USPS, especially for lightweight packages traveling for short distances.
- Dimensional-based rates: If you want to ship small but heavy packages, you may find USPS's cheapest shipping via the Mail Cubic service, where the shipping rate is determined based on the dimensional weight of your package rather than its weight.
- Flat Rate Packaging: When shipping heavy packages for longer distances, using USPS Flat Rate box options may be the cheapest way to ship USPS.
- Speed: The faster you want your package delivered, the more the delivery cost
- Service Restriction: Different USPS services have specific weight and dimension restrictions. For example, first-class packages must weigh less than 13oz, while media mail is restricted to shipping media and educational material. Other USPS services allow package weights up to 70 lbs.

Cheapest USPS Domestic Shipping
Different USPS services are fit for shipping different packages based on the above factors.
Here, we discuss the different USPS domestic services and how each service is best suited as the USPS cheapest shipping option for certain types of packages.
USPS Ground - Advantage
USPS - Ground Advantage replaces the previous USPS Retail Ground, Parcel Select Ground shipping, and First-Class Package options. Combining their strengths to create a new, faster and more affordable service, you can conveniently ship packages weighing up to 70lbs and expect them to be delivered within 2-5 business days. Moreover, this is often the primary option for sending hazardous materials (HAZMAT) that can't go by air.
This is a separate service from First-Class Package Service. It is considered to be the cheapest USPS shipping option for sending letters and large Envelopes/Flats.
This is the USPS cheapest shipping option for mailing media and educational materials such as books, printed music, sound and video recordings like CDs and DVDs. Delivery timelines average 2-8 business days, but there may be delays since this service is not guaranteed.
Shipping rates are determined by package weight; the maximum weight for domestic shipments is 70 lbs.
This fastest USPS mail service offers a money-back guarantee and overnight delivery to most US locations, including P.O. boxes. This is the best service for you if you need to guarantee that your package will be delivered fast and on time.
Priority Mail Express offers both weight-based rates and flat-rate envelopes. Weight-based rates are best for you if your package is lightweight and traveling short distances, while flat rate shipping envelopes are excellent for heavy packages traveling long distances.
This quick and affordable USPS domestic service delivers packages to mail slots, mailboxes, and PO boxes within 1-3 business days. But it is not a guaranteed service, meaning delivery may be delayed.
This is a special Priority Mail service where packages are priced based on their outer dimensions rather than weight. It is the fastest and cheapest USPS shipping option for mailing packages that weigh over 1lb and under 20 lbs.
There are 5 pricing tiers, from 0.1 to 0.5, and the shipping rate for your package depends on the cubic tier in which your package fits. Packages are delivered within 1-3 business days.
Here is how you calculate the cubic tier of your package:
(Length x Width x Height)/1728
USPS Flat Rate (Domestic) allows merchants to ship packages for a fixed price, regardless of the package weight or shipping zone, using specified USPS Flat Rate boxes. It is an excellent option for shipping heavy-weight packages to the furthest shipping zones.
The table below shows estimated shipping rates for the different USPS services when sending a 2lb package from Brooklyn, NY to Miami, Florida.
As you can see, the Ground Advantage package wins out here as the USPS cheapest shipping service for mailing a 2lb package from Brooklyn to Miami. This may be different for larger packages and weights, so use the Easyship’s shipping rates calculator to compute rates accordingly.
USPS Cheapest International Shipping
USPS offers several international shipping services, and just like domestic shipping, finding USPS's cheapest international shipping service depends on the weight of your package and delivery speed.
Here, we discuss the different USPS international services, and how you can find the cheapest way to ship USPS with each service.
This is the cheapest USPS shipping option for sending lightweight packages that weigh less than 4lbs to international destinations. It is not a guaranteed service, and delivery timelines vary by destination. International shipping rates are determined by package weight and Country Group.
This is the fastest and most cost-effective service that offers guaranteed delivery for select international locations to more than 180+ countries within 3 to 5 business days.
It is one of the cheapest USPS cheapest shipping options for sending mail and packages internationally to more than 180 countries within 6-8 days. Since it is not a guaranteed service, there may be delivery delays based on origin, destination, and customs delays.
This may be the cheapest USPS option for large packages shipping internationally. It allows merchants to send packages across borders for a fixed price, regardless of weight or shipping distance using specified USPS Flat Rate Boxes.

What are the Other Factors to Consider When Choosing USPS Cheapest Shipping?
Apart from the shipping rate, you should also consider other value-added services that will help you offer a streamlined shipping experience to your domestic and international customers. They include:
- Tracking
It is important that you and your customers have a way of tracking packages to help reduce delivery anxiety or instances of lost packages. Although USPS does not offer elaborate tracking capabilities, it includes USPS confirmation delivery, also known as USPS tracking in most of its domestic services.
Delivery confirmation helps you track and confirm your package's delivery dates and time, and report any instances of delayed delivery or lost packages. USPS tracking is also available on some international shipments, but further restrictions apply.
- Insurance
When shipping high-value items, you must insure them. Some USPS services include some basic insurance coverage, while others do not include any at all. Most of the time, the base coverage is insufficient for high-valued goods, and you may need to purchase an additional insurance cover. Easyship can help you cover your packages up to $10,000.
