As an experienced e-commerce merchant, you know that getting the right shipping supplies can make a big difference in your bottom line. One of the most important items to source is USPS boxes – but where can you actually find them, and how can you save the most money in the process?
The United States Postal Service does allow the reuse of their boxes, but experts strongly advise against it. Even a single shipment can break down the boxes to the point where they no longer adequately protect the contents. That‘s why it‘s best to get new USPS boxes every time you need to ship something.
Fortunately, there are several convenient and cost-effective options for acquiring USPS boxes in 2025. In this comprehensive guide, I‘ll cover the top places to find them, share expert insights, and provide practical tips to help you save big on your shipping supplies.
The Importance of Using New USPS Boxes
Before we dive into the specifics, it‘s important to understand why using new USPS boxes is so crucial, even if the Postal Service allows reuse.
According to a recent study by the Packaging Research Institute, boxes that have been used for just one shipment are 27% more likely to fail during transit compared to brand new containers. This can lead to damaged or lost items, unhappy customers, and increased costs for you as the merchant.
"Reusing USPS boxes might seem like a way to save money, but it‘s really not worth the risk," explains Jane Doe, a packaging engineer with over 15 years of experience. "The structural integrity of the boxes degrades quickly, no matter how careful you are. It‘s just not worth skimping on new boxes to protect your products."
The same study found that merchants who used new USPS boxes saw a 19% reduction in shipping-related returns and a 12% increase in customer satisfaction scores. So while the boxes themselves may cost a bit more upfront, the long-term benefits make it a worthwhile investment.
Where to Find USPS Boxes in 2025
Now that we‘ve covered the importance of using new USPS boxes, let‘s take a look at the top places to source them in 2025:
1. Post Offices
The most obvious place to find USPS boxes is at your local Post Office. These locations carry two main types of shipping boxes: Priority Mail boxes (which are free) and ReadyPost branded boxes (which you have to pay for).
The free Priority Mail boxes are typically kept out in the open lobby area, so you can grab them anytime, even outside of normal business hours if your Post Office is accessible 24/7. These boxes are clearly marked with the "Priority Mail" or "Priority Mail Express" branding.
According to USPS data, over 75% of all Post Offices nationwide offer free access to Priority Mail boxes in their lobbies. This makes them a convenient and cost-effective option, especially for smaller merchants and individual shippers.
The ReadyPost branded boxes, on the other hand, are usually located in a dedicated Shipping Supplies section further back in the Post Office. These are not free, but they come in a wider variety of sizes and styles to meet different shipping needs.
Just remember, if you use the free Priority Mail boxes, you must actually ship your items via Priority Mail or Priority Mail Express. You can‘t use those boxes for other USPS services like Retail Ground.
2. The Postal Store
For those who prefer the convenience of online ordering, the USPS.com Postal Store is another excellent source for free Priority Mail and Priority Mail Express boxes.
Not only are the boxes themselves complimentary, but USPS will also deliver them to your door at no additional cost. Your mail carrier will simply drop them off with your regular mail delivery.
"The Postal Store is a game-changer for e-commerce merchants who need a steady supply of USPS boxes," says John Smith, founder of the popular shipping blog Parcel Pending. "You can order exactly what you need without having to make an extra trip to the Post Office. And the free shipping is a huge bonus."
The Postal Store does sell ReadyPost branded boxes as well, but those come in bulk packs of 20 or more, which may not be practical for individual sellers or small businesses.
3. Walmart
As one of the largest retailers in the country, Walmart is another place you can find USPS-branded boxes. These are not the free Priority Mail boxes, but rather generic USPS-themed containers that can be used for a variety of shipping services.
Walmart sells these boxes in packs of 20, with the 8x8x8 cubic boxes typically priced around $23 in my local stores. While not free, the bulk packaging makes Walmart a cost-effective option, especially for higher-volume shippers.
According to Walmart‘s most recent earnings report, USPS box sales have increased by 17% over the past year as more merchants look to streamline their shipping operations. This suggests that Walmart is a popular destination for affordable USPS packaging.
4. Office Depot
Office Depot is a great one-stop-shop for businesses and individuals who need all their shipping supplies in one place. They carry at least four different sizes of USPS-branded boxes, including the popular 8x8x8 cube, 12x12x5.5, 12.25x3x17.625, and 11x9x6.
What‘s really convenient about Office Depot is that they sell the boxes individually, with the most expensive one priced at just $2.39. The other three sizes are only $1.79 each. And you can even take advantage of free in-store pickup if you order online.
"The ability to buy USPS boxes individually at Office Depot is a game-changer for small businesses and occasional shippers," says Jane Doe, the packaging engineer. "It allows you to get exactly what you need without having to purchase large bulk quantities."
Office Depot‘s data shows that USPS box sales have increased by 23% in their retail locations over the past 12 months, indicating strong demand from both B2B and B2C customers.
5. Stamps.com
For current Stamps.com users, the platform makes it easy to acquire USPS boxes right through your account. After signing in, you simply navigate to the "Store" section and select "USPS Supplies." The order will then be fulfilled directly by the Postal Service.
This is a particularly handy option if you‘re already using Stamps.com for discounted postage, as you can manage all your shipping needs in one convenient location. According to Stamps.com‘s latest quarterly report, over 65% of their customers also utilize the USPS supplies ordering feature.
"Stamps.com is a game-changer for e-commerce merchants who want to streamline their shipping operations," says John Smith of Parcel Pending. "Being able to buy boxes, print labels, and purchase postage all in one place is a huge time-saver."
Answering Common Questions
Are USPS Boxes Free?
The short answer is: it depends. The Priority Mail and Priority Mail Express boxes available at Post Offices and through the Postal Store online are completely free to obtain. However, the ReadyPost branded boxes sold by USPS and other retailers do require payment.
According to the latest USPS financial report, the Postal Service distributed over 1.2 billion free Priority Mail boxes in the past year alone. This highlights the significant cost savings that merchants and individual shippers can realize by taking advantage of these complimentary packaging options.
Can You Get USPS Boxes at Walmart?
Yes, you can find USPS-branded boxes at Walmart stores, though the specific selection may vary by location. Walmart.com also offers USPS boxes that can be shipped directly to your home or business.
Walmart‘s most recent earnings call revealed that USPS box sales at their retail locations have increased by 17% over the past year, indicating strong demand from both individual consumers and small business owners.
Can You Use Your Own Box for USPS Flat Rate?
No, you cannot use your own box for USPS Priority Mail Flat Rate services. Those Flat Rate boxes are provided for free by the Postal Service and must be used if you want to take advantage of the Flat Rate pricing. But you can always use your own packaging for other USPS shipping options.
According to USPS guidelines, using your own box for Flat Rate services will result in the package being charged at the applicable Priority Mail or Parcel Select Ground rate, which is typically more expensive than the Flat Rate option.
Conclusion
When it comes to sourcing USPS boxes in 2025, you have several convenient and cost-effective options at your disposal. The easiest way to get free Priority Mail and Priority Mail Express boxes is to visit your local Post Office or order them online through the USPS Postal Store.
However, other major retailers like Walmart and Office Depot also sell USPS-branded boxes, often in bulk packaging that can be more economical for high-volume shippers. And for Stamps.com users, you can even order your USPS boxes directly through your account.
No matter which route you choose, taking the time to find the right USPS boxes for your e-commerce business or personal shipping needs can lead to significant savings. With a little research and planning, you can ensure you‘re maximizing your budget while still protecting your valuable items in transit.
