Currency conversion and the cost you did not see

Currency conversion and the cost you did not see — setting out what I have, and where I think it stops being reliable.

Currency and fees, set out so that the comparison can be checked.

Quoted amount, conversion rate applied, the spread on top of the mid-market rate, and any fixed fee: four numbers, and only the first is ever quoted. On my last two orders the difference between the quoted figure and the amount that left the account was not trivial.

Am I setting this comparison up correctly, or is there a component everyone else already accounts for?

Escrow services: some third-party services hold payment until the buyer confirms receipt. They add cost but reduce risk if the supplier is unknown.

This is where my knowledge stops and I would rather mark the edge than blur it.

Currency conversion: payment in your local currency often involves a conversion fee. Paying in the supplier's native currency sometimes saves money, sometimes costs more. Compare before committing.

Anyone with a larger sample, please post it.
