How the price is computed
A letter's price has two steps. First we compute the cost — postage for the weight tier plus print per sheet. From the cost we compute the charge with a margin that covers fees and the gap between our estimate and Česká pošta's real price.

Charge = rounded up to the next whole CZK from the higher of: cost × 1.25, or cost + 8 CZK.
Each additional sheet costs 1.05 CZK (incl. VAT).
The displayed price never drops below 50 CZK — the site-wide one-off payment minimum.
Postage matches the Hybridní pošta / Kredit tariff Česká pošta bills for letters submitted through DopisOnline (tariff effective 1 April 2026) — the same table @postbot/core's price calculation (chargeFor) uses.
