Ask an eBay seller what they want from a courier and the answer is almost always the same: the cheapest option that still gives me tracking for seller protection. The good news is that eBay's own label tool and the mainstream carriers both serve that goal, but the cheapest carrier genuinely depends on the parcel's size and weight, and the answer changes as the parcel gets bigger.
Why tracking is non-negotiable on eBay
Before we get to price, the constraint that shapes everything is tracking. eBay's seller protection depends on proof of delivery, and untracked postage leaves you exposed in a dispute. So the real question isn't the absolute cheapest stamp, it's the cheapest tracked service. That rules out plain 2nd Class for anything worth disputing, and narrows the field to tracked economy options.
Small parcels: Evri and InPost usually win
For a typical small parcel in the 500g to 2kg range, Evri and InPost are usually the cheapest tracked options, and they're the reason so many eBay sellers have moved off Royal Mail for low-value items. The price difference per parcel is often tens of pence, which sounds trivial until you multiply it by a few hundred sales a month. Our DPD vs Evri vs Royal Mail guide puts numbers on it.
Large letters: Royal Mail still wins
For flat items that fit the Letter or Large Letter bands, Royal Mail is hard to beat, because its letter pricing is built for exactly that and Evri and InPost are parcel networks. If you sell trading cards, stickers or thin accessories, Royal Mail's Standard Envelope or Large Letter services are the cheapest tracked or semi-tracked options you'll find.
Medium and heavier parcels
Once a parcel pushes past 2kg, the picture shifts. Royal Mail's Medium Parcel band is competitive, Evri handles up to 15kg at good rates, and Yodel becomes worth a look for heavier items. The cheapest option at 3kg is often different from the cheapest at 1kg, which is why a blanket favourite carrier is a mistake.
eBay's own labels vs buying direct
eBay's integrated label tool offers discounted rates from several carriers in one place, and for many sellers that's the cheapest way to buy without opening multiple accounts. The rates are genuinely competitive, and the convenience of having tracking auto-upload to eBay saves time. It's worth comparing against buying direct, but the integrated option is a strong default.
Drop-off convenience as a hidden cost
The cheapest carrier on paper can become expensive if the drop-off is inconvenient. A Post Office or locker you can walk to is worth a few pence per parcel versus a ParcelShop across town. Factor in your time, because the point of finding a cheap courier is saving money, not trading it for an hour of driving. Our drop-off comparison covers the convenience angle.
How to actually find your cheapest option
The reliable method is to quote the same parcel, same weight, same dimensions, across two or three carriers in eBay's label tool and pick the winner. Do that for your three most common parcel types and you'll have your answer, because your cheapest carrier is specific to what you sell, not a universal truth. It takes ten minutes and it pays you back on every parcel after.
Locking in the saving without losing protection
Once you've found the cheap tracked option, make sure the tracking number is uploaded to eBay automatically, either through the label tool or your shipping platform. The whole point of a cheap tracked service is that it's cheap and it protects you, and the protection only works if the tracking actually reaches eBay's system.
Frequently asked questions
What's the cheapest tracked option for eBay sellers? For small parcels, Evri and InPost are usually cheapest. For flat items, Royal Mail's Large Letter and Standard Envelope services win.
Do I need tracking on eBay parcels? Yes, for anything you'd want seller protection on. Untracked postage leaves you exposed in an item-not-received dispute.
Is eBay's own label tool cheaper than buying direct? Often yes, and it auto-uploads tracking, so it's a strong default. Still worth comparing against direct carrier rates for your volume.
Cheap postage still needs a good label
Whichever cheap tracked service you land on, a 100 × 150mm direct thermal label keeps the barcode scannable, so the tracking that protects you actually works.
