Who should not switch
If you ship USPS parcels every week, own a scale, and do not mind holding an account, the cheapest sensible answer is a zero-markup reseller. We would rather you read that here than discover it after paying us.
Concession first
Pirate Ship alternative, with their price advantage conceded up front
Pirate Ship's own site says it charges No monthly fees, markup or hidden costs
and that we're paid by the carriers, not by you
(per pirateship.com, checked 2026-07-28). On a straightforward USPS or UPS label that is very hard to beat on price, and a page that pretended otherwise would not be worth reading.
Their wording quoted, not paraphrasedCommercial price tables citedWhere we lose, stated plainly
Same postage pool, different front door
Both routes end at the same carrier networks. What differs is the signup, the carrier list on screen, and what happens when you have no scale in the house.
What Pirate Ship publishes about itself
Straight from pirateship.com on 2026-07-28. We have quoted the load-bearing phrases rather than restating them, since the whole comparison turns on what the company says it charges.
- The homepage states
No monthly fees, payment fees, or hidden costs.
- On how the business earns, it says
we're paid by the carriers, not by you.
- Getting started means creating a free account, with the site noting
No credit card required.
- Two carriers are presented: USPS, with Commercial Pricing® and Priority Mail Cubic®, and UPS.
Take that at face value, because there is no reason not to. A reseller passing carrier commercial pricing through untouched will land at the commercial tier, and the commercial tier is published, so anybody can check it.
What the commercial tier actually is
USPS prints the commercial column in Notice 123. Below are Ground Advantage commercial prices at four weights, shown for a near zone and a far one, so the underlying pool of prices is visible rather than implied.
| Parcel weight | Zone 4 commercial | Zone 8 commercial |
|---|---|---|
| 1 lb | $8.15 | $10.67 |
| 5 lb | $11.02 | $19.19 |
| 10 lb | $14.44 | $25.34 |
| 20 lb | $19.66 | $40.39 |
Anybody selling USPS labels without a markup is selling from that column. It follows that on a plain domestic USPS parcel, a zero-markup vendor will usually come in under a vendor whose charge is folded into the rate, and we are the second kind. That is the concession, stated once and not hedged.
Our all-in price on a real box
So that the trade-off is measurable rather than rhetorical, here is a standard 5 lb carton on a medium-length lane. Each figure is what the card gets charged, our part included, with nothing to add afterwards.
| Carrier | Service | Price | Transit window returned |
|---|---|---|---|
| UPS | Ground Saver | $13.52 | None returned |
| USPS | Ground Advantage | $14.02 | 8-9 business days |
| UPS | Ground | $14.05 | 2-3 business days |
| FedEx | Ground Economy | $14.31 | 6-7 business days |
| UPS | 2nd Day Air | $21.96 | 2-3 business days |
Four of those five rows sit inside eighty cents of each other, which is the interesting part. When a lane bunches like that, the deciding factor stops being price and becomes the transit column: UPS Ground quoted 2-3 business days where the USPS row quoted 8-9, for three cents more.
The three things we do that they do not
Every one of these is checkable against their site and ours. None of them is a criticism; they are simply different product decisions.
- No signup for the first quotes. Pirate Ship asks for a free account before you see rates. Our first three quotes need no account and checkout runs as a guest, which matters mostly for a one-off shipment at an awkward hour.
- FedEx appears in the list. Their site presents USPS and UPS. Ours quotes USPS, UPS and FedEx together, and on the carton above the FedEx row finished fourth of five at 79 cents above the cheapest.
- You can price a box you have not measured. Describe the item and our estimator produces dimensions and a weight before the rate call, which is the whole point of shipping without a scale. If you already own a scale and a tape, that advantage is worth nothing to you.
There is a fourth difference worth naming because it cuts against us as well as for us: anything palletised, crated or oversized goes through our freight review instead of straight to checkout. That is slower than a self-service label and it is deliberate.
Who this page is for
Somebody selling one thing on a marketplace, moving a box for a relative, or clearing a garage. No scale, no routine, no appetite for another login, and a genuine need to see what FedEx charges alongside the other two.
Cubic pricing is a real edge
Priority Mail Cubic prices small dense parcels by volume instead of weight and can beat weight-based rates badly on the right box. Their site lists it. Our cubic pricing explainer covers when the box shape qualifies.
Pirate Ship compared honestly
Is Pirate Ship cheaper than SMKlog?
On a plain USPS or UPS domestic label, usually yes. Their site states they add no markup and are paid by the carriers, which puts them at the published commercial tier, while our charge sits inside the rate we show. We would rather write that down than argue with it.
Then why use SMKlog at all?
Three reasons, each checkable. The first three quotes need no account, FedEx is quoted alongside USPS and UPS, and a parcel can be priced from a description when there is no scale in the house.
Which carriers does Pirate Ship list?
Its site presents USPS and UPS, including USPS Commercial Pricing and Priority Mail Cubic, checked on pirateship.com on 2026-07-28. We quote USPS, UPS and FedEx, all US domestic.
What does a 5 lb box cost here?
For a 12 x 10 x 6 in carton running Newark to Atlanta on 2026-07-28, live rates came back between $13.52 and $21.96 depending on service, with four of the five rows inside eighty cents. Those prices are complete, with our charge already inside them.
