Does postage count in a card value?
Valuing cards. . 1 min read.
A card sells for £40 with free postage. Another sells for £36 plus £4.20. Those are the same transaction and two different numbers, and if you mix them across a comp set you have added several pounds of noise to every figure in it.
Pick one convention
Either compare hammer prices to hammer prices, or totals to totals. Which you choose matters far less than choosing. The method in how to price a sports card treats consistency as the requirement, not a particular answer.
When it barely matters
On a £400 card, a £4 postage difference is one percent and beneath the noise floor of the comps themselves. Ignore it.
When it matters a lot
On a £12 card it is a third of the price. At the low end, postage is not a rounding error, it is a meaningful share of what changed hands, and sellers move it in and out of the headline figure to look competitive in search results.
Sellers know that search sorts on the headline price. A £1 card with £4 postage sits above a £5 card with free postage in a low-to-high sort, which is exactly why it is priced that way.
What the app does
It reads hammer prices, consistently, and says so. Consistency is what makes a series of comps comparable to each other over time, which is the only thing that lets you see a trend rather than a scatter.
