Postage Is Eating My Profit

Know parcel size and delivery cost before pricing low-value stock, and record packaging as a real selling cost.

Quick diagnosisNo jargonUpdated September 2026
Short answer

Know parcel size and delivery cost before pricing low-value stock, and record packaging as a real selling cost.

Check these things in order

1. Weigh common parcel types

Change one thing at a time where possible so you can see what actually helped.

2. Use the correct size band

Change one thing at a time where possible so you can see what actually helped.

3. Track packaging cost

Change one thing at a time where possible so you can see what actually helped.

4. Review whether low-value bulky stock is worth listing

Change one thing at a time where possible so you can see what actually helped.

What this can look like

A £7 item can become a terrible sale if you unexpectedly pay £4.50 delivery and £1 packaging.

Do not do this

Do not estimate postage from memory when margins are thin.

What should I track?

Keep the item cost, current price, age, platform and final sale result together. That makes it much easier to tell whether the problem is visibility, price, demand or simply slow stock.
