About Pirate Ship
Are you getting the best USPS® rates possible?
We got sea-sick buying postage with shipping software that charges monthly fees & adds markup on top of USPS® services, so we built Pirate Ship.
We pass-through the cheapest USPS® pricing tier available (Commercial Plus Pricing®) and don't charge any fees or add any markup. Just pay the actual cost of the postage as you go!
You'll get the best rates for all services, including Priority Mail Cubic®, which can save you tons of treasure compared to buying shipping labels with other software.
Wait, everyone says they offer the "best" rates...
ARrrr matey, they're lying to you! Other shipping software adds markup on top of the Commercial Plus Pricing® rates for services like Priority Mail Cubic® (Compare their rates and make them walk the plank!)
The shipping features you need & nothing you don't:
- 100% free, easy to install, and easy to use... start shipping in seconds!
- Automatically marks Shopify orders as "Fulfilled" & adds tracking numbers
- Works great with Shopify Apps for recurring subscription billing like Bold or ReCharge
Great for batch shippers & subscription boxes!
Pirate Ship makes shipping identical packages simple. Quickly search, filter, and sort your Shopify orders into batches, then buy as many labels as you need for that variation. With no limits on the size of your batches, it's fast & fun to buy as much postage as you need.
Access Commercial Plus Pricing® for all services:
- Priority Mail Cubic®, the cheapest way to ship small packages 1-20 lbs
- First Class Package®, the cheapest service for packages that weigh 15.9 oz or less
- First Class Package International®, the cheapest way to ship internationally
- And all other shipping services, including Priority Mail Flat Rate®, Media Mail®, etc!

The Painted Heirloom
This app is a game changer, really. I thought USPS Priority Regional Rates were cheap - wow on the USPS Priority Cubic Rates - JUST WOW! I should have installed this app from Day 1 - seriously.
We sell small pint size jars of paint. They're small, and heavy. But, I can fit 3 into a USPS Priority Box 4, that weigh 4 lbs, 12 oz, and ship from Florida to Washington State for $8.92 via USPS Priority Cubic.
The same shipment would be $11.20 in the smallest USPS Regional Rate Priority Box, $12.80 in USPS Medium Flat Rate Box, or $20.40 regular USPS Priority!
We also offer $4.99 shipping for orders over $75, this will help us save money when we supplement shipping costs with our customers.
For example - just jammed (actually fits in nicely) 4+ LBS of products into a 1092 bound from Pensacola FL to Arizona. USPS Priority was $17+. UPS was $18+. USPS Cubic Priority was $10.78! That saved us $7 for just that one shipment, and it will get there same time as regular USPS Priority.
Is there ANY way to have my customers view all the rates available? Shopify is SOOOOOO frustrating!!
The ONLY reason I give it 4 stars is because I want to pass the savings onto my customers. I do not wish to make one single penny off of shipping. If we can show and offer these rates to our customers, that would be amazing. Everyone would win. No need for the Post Office to get any more money than they need!
You need to team up with Bespoke Shipping! They're smart and together you two could dominate shipping. Seriously.
Loving Essential Oils
I am loving the app, it is easy to use and the savings is just amazing. I left my other app I had been with for 3 years because it was just too expensive, I am saving $100's each month with Pirate Ship. I am so happy to have found your app, and that it is free!! Being a small company, every penny counts for me so I really appreciate having access to Pirate Ship.
I also love all the help, documentation they offer and saving tips that took me over 5 years shipping experience to learn. In Pirate Ship documentation they breakdown how to ship the cheapest way, super valuable information, especially for newbies! Keep up the great work!

This app and the customer service from Pirate Ship goes far beyond our expectations. Strongly recommended.
