Most of the components were ordered from DigiKey, some from LCSC and some I already had.

I added single component prices from DigiKey to BOM.csv file.

All components needed for one board totals to ~12$.

I ordered PCBs on JLCPCB service with minimal quantity of 5 and all standard features. Total price was 2$.

So one business card costs around 14$, this doesn't include shipping cost and taxes.
