Per-order cost, roughly, by tier
| Order type | Packaging | Postage (approx.) | Total, roughly |
|---|---|---|---|
| Bulk / low-value single, untracked | ~$0.05 (sleeve + envelope) | ~$0.75-1 (first-class letter rate) | ~$0.80-1.05 |
| Standard single, tracked | ~$0.20-0.35 (sleeve, toploader, team bag) | ~$4-5 (tracked small package) | ~$4.20-5.35 |
| Higher-value single, tracked + signature | ~$0.30-0.50 | ~$6-9 | ~$6.30-9.50 |
| Sealed product / multiple cards | ~$0.50-1.50 (box, void fill) | Varies by weight and size | Varies — weigh and measure before pricing |
These are rough, current-as-of-writing ranges to reason about margin with — actual postal rates shift over time and vary by carrier and service level, so check current rates before pricing tight-margin inventory.
The fee layer sellers forget to count
On top of packaging and postage, TCGplayer's marketplace fee (~8.5%), payment processing fee (~2.5%), and $0.50 per-order fee all come out before you see the money. For a $3 bulk sale, that ~$0.50 flat fee alone is over 15% of the sale price — which is why bulk pricing has to account for fixed per-order costs, not just a percentage margin. See pricing to sell fast for how this interacts with staying competitive.
Where sellers accidentally lose margin
- Oversized packaging for small items. A card in a box sized for something else can bump you into a higher postage tier for no reason.
- Under-tracking high-value orders. Skipping tracking to save a few dollars on an expensive single is a bad trade against the cost of an "item not received" dispute.
- Over-tracking bulk orders. The reverse mistake — paying for tracked service on a $1 common — can erase the entire profit margin on that sale.
- Time cost that never gets counted. Manually re-typing addresses from a packing list, or hand-cutting labels, doesn't show up on a receipt, but it's real cost per order that scales with volume. This is the specific gap TCG Speed Shipper exists to close — turning a packing-list CSV into printed labels in seconds instead of minutes per order.
Rule of thumb: match shipping method to order value, not habit. Tracking on everything is safe but expensive at bulk volume; tracking on nothing is cheap but risky on your highest-value sales. See packaging by order value for the same logic applied to materials.
Building shipping cost into your pricing, not treating it as an afterthought
The most sustainable approach is deciding your shipping-and-packaging cost per tier before you price inventory, not discovering it after a month of thin margins. Once you know your real per-order cost at each tier, pricing decisions get much easier — you know exactly how much room you have to undercut competing listings before a sale stops being worth making.
