# USPS Flat Rate

Shipping just got easier! Sellers can now purchase **USPS Flat Rate labels** directly in Palmstreet—no measuring, no weighing, and no need to leave the app. Just choose a box, get a fixed price, and print the label—all in one place.

## What Is USPS Flat Rate Shipping?

USPS Flat Rate shipping is a **quick and cost-effective way to send packages within the U.S.** The shipping cost is based on box size—not weight or destination. As long as the item fits in a Flat Rate box and weighs less than **70 lbs per box**, it ships at a fixed rate.

**Key Benefits:**

* **Fixed pricing** – Cost is based on box size, not weight or distance
* **Up to 70 lbs** – Works well for heavy items
* **Free packaging** — Flat Rate boxes and envelopes ordered from USPS post offices are free
* **Priority Mail included** — Comes with tracking and insurance

## When to Use Flat Rate Shipping

Flat Rate is a great option for:

* **Heavier items** that would normally cost more to ship
