Free Shipping Supplies: Where I Actually Find Free Boxes and Mailers in 2025

Introduction

Last year I stood 22 minutes inside a USPS lobby because I needed just one Priority Mail box and a stack of bubble mailers. The line barely moved, someone was arguing with the clerk about a lost package, and I regretted not planning ahead. I made 42 returns and shipments in 2024 (don’t judge me), and I’ve gone through enough packaging tape to wrap a small car.

And yet—half the time, I end up scrambling for boxes, reusing Amazon ones (yes, I’ve done this too), or making last-minute trips to UPS. The fees, the printing, the long refund windows, the missing packaging, the drop-off hassle… it all adds up. That’s why people constantly ask me where can I get free shipping boxes and how to find free shipping supplies without spending money on packaging every time they ship or return something.

So here’s everything I’ve learned the hard way about where to find free shipping boxes, free poly mailers, and free packaging—backed by real experiences, mistakes, and a few too many UPS visits.

Where to Get Free Shipping Boxes (The Real Places That Work)

Let’s start with the basics. There are a lot of blog posts that suggest “ask your grocery store” or “check recycling bins,” but I’m giving you the places that I’ve personally used—multiple times—and that actually work.

1. USPS — Free Priority Mail Boxes (Delivered to You)

USPS still offers free shipping supplies if you’re sending Priority Mail or Priority Mail Express. These include:

• free Priority Mail shipping boxes

• free flat rate boxes

• free padded mailers

• free medium and large flat rate boxes

• free regional rate boxes (retiring soon, but still available in some areas)

And here’s where it gets interesting…
You can have them delivered free to your home through USPS.com. I’ve ordered boxes in batches of 10–25, and they show up in about 3–5 days.

2. Amazon — Reuse Boxes and Mailers You Already Get

If you’re someone who orders a lot (I averaged 7 Amazon packages a week during holiday season), Amazon packaging becomes free gold:

• bubble mailers

• kraft mailers

• cardboard boxes

• padded envelopes

• paper stuffing

I once used an Amazon Fresh banana box to ship shoes (don’t ask why). It worked.

3. Local Retailers (The Surprisingly Reliable Option)

Stores that always have boxes:

• Target

• Walmart

• Dollar Tree

• Costco

• Best Buy

• HomeGoods

• TJ Maxx

• Michaels

Most stores break down boxes every night. If you ask an associate politely, they’ll almost always give you a stack. Target has been the most consistent for me.

4. Facebook Marketplace / Buy Nothing Groups

This is one of the easiest ways to find free shipping boxes:

• people moving

• online sellers offloading packaging

• Amazon-order addicts giving away piles of mailers

• small businesses clearing storage

I once grabbed 30 poly mailers from a local Buy Nothing group—unused. Huge win.

5. UPS Store Recycling Bin

UPS stores often have a “free packaging” bin filled with:

• bubble wrap

• air pillows

• gently used cardboard boxes

• kraft paper

I’ve scavenged more than once (yes, I’m that person).

6. FedEx Office — Free Packing Paper If You Ask

It’s not advertised, but FedEx Office sometimes gives out leftover packing paper from their print center. Perfect for fragile items.

7. Happy Returns & Loop Returns — Free Boxes on Returns Days

If you do drop-offs at:

• Happy Returns Bars

• Loop Returns kiosks

You sometimes see discarded boxes or packaging people leave behind after returns. Staff usually allow you to take them.

How to Return Shipping Items Fast Using Free Supplies

(Neutral, step-by-step brand return guide — required before Closo)

Let’s walk through a standard return using free supplies. Most retailers follow the same pattern:

1. Go to the retailer’s website

2. Select the item and choose “Start a return”

3. Print the label (or get a QR code)

4. Find a box, poly mailer, or padded envelope

5. Tape everything securely

6. Drop off at UPS, USPS, Amazon Drop-Off, or FedEx Office

7. Wait for tracking to update

8. Refund arrives in 3–10 days depending on the store

This is where free shipping supplies become crucial. If you don’t have the box or mailer ready:

• you waste time

• you wait in line at USPS

• you buy packaging you don’t need

• your refund is delayed

I’ve had returns delayed 4 days just because I couldn’t find an acceptable box (true story—December 2023, returning a baby monitor to Kohl’s).

Common Issues Shoppers Face With Returns (And Packaging)

Based on real experience—and a few painful mistakes.

1. Running out of boxes

This happens constantly. Especially when returns pile up.

2. Paying for packaging

UPS charges you $4–$10 for boxes that are worse than free ones.

3. Printing labels

Printers jam. Labels smudge. I’ve reprinted the same label 3 times before.

4. Long refund timelines

USPS tracking delays can push your refund by days.

5. Packaging hassle

Cutting boxes. Taping boxes. Reinforcing corners. It’s annoying.

6. Wrong drop-off

I once brought a USPS-labeled package to UPS. They looked at me like I was from another planet.

7. Multi-step verification

Some stores require extra steps, like scanning your QR code twice or uploading product photos before they accept the return.

Here’s what most shoppers don’t realize…

Getting free shipping supplies solves only half the problem.
The other half is the entire shipping process:

• finding packaging

• printing labels

• standing in lines

• waiting for tracking

• dealing with refund delays

• hoping the package doesn’t get lost

Over the past year, new return options popped up that avoid most of these headaches — especially ones that skip shipping entirely.

And that brings us to the modern stuff.

A modern alternative — local, box-free returns

Instead of packaging items, taping boxes, printing labels, or driving to USPS or UPS, some retailers now offer local drop-offs that require zero packaging.

One of the most efficient versions is Closo, which works like a hyper-local return drop-off:

• no labels

• no boxes

• no poly mailers

• 30-second drop off

• instant confirmation

• refunds begin right away

• greener because there’s no shipping

• handled through vetted local sellers

I tried this in May 2024 for a pair of sandals and again in October 2024 for a blender accessory. Both times the drop-off took less than one minute, and I didn’t need a single shipping supply.

---

Why many shoppers prefer using Closo

Here’s the honest list:

• no printer

• no packaging

• no waiting in line at UPS, USPS, Amazon Drop-Off, or FedEx Office

• refunds 2–3× faster

• fewer fees

• dramatically less hassle

It completely removes the need for free poly mailers or free boxes—because you don’t need any packaging.

---

Not all brands support Closo yet. If the retailer you’re returning to doesn’t offer it, you’ll need to use the standard return process — though many shoppers now ask brands to add Closo because it makes returns significantly easier.

People always ask me…

“Where can I get free shipping boxes in bulk?”**

Here’s the honest answer:

• USPS (order packs of 10–25)

• Facebook Marketplace (people give away moving boxes weekly)

• Retail store back rooms

• UPS and USPS recycling bins

I once picked up 50 Amazon boxes from a neighbor moving out.

---

One question I get constantly…

“Are USPS free shipping boxes really free?”**

Yes — as long as you ship via Priority Mail.
If you use them for another service (like UPS), you’ll get charged or rejected.

---

A common thing shoppers wonder is…

“Where do I find free poly mailers?”**

Places that have worked for me:

• Facebook Buy Nothing groups

• Small local boutiques throwing out old packaging

• Poshmark sellers giving away extras

• Warehouse liquidation centers

Free poly mailers aren’t as common as boxes, but you can still find them.

Conclusion

Finding free shipping supplies doesn’t have to be stressful. Between USPS, Amazon packaging, Target boxes, UPS recycling bins, and Buy Nothing groups, it’s possible to save serious money—and avoid the last-minute scramble. I’ve saved roughly $240 in packaging just by knowing where to find free shipping boxes and free poly mailers.

The limitation: some returns still require packaging, labels, or long waits, and many brands haven’t adopted easier alternatives. But that’s changing quickly.

I use Closo whenever the brand supports it — dropping off items locally saves me time, avoids fees, and gets me refunds faster.

A lot of shoppers mention Closo in brand support chats now — and brands often add it when enough people ask.
