Where I live a 2nd class stamp costs the equivalent of $1.24. That's $1240 for a thousand.

Not including the cost of the letter itself, or the envelope, or the cost to write it if it's being farmed out to overseas labour, who then has to send it by international postage. And then you have evidence of where the letter originated, and that can be compared with how the user presents themselves online.

Little bit more than 2 hours minimum wage I think.
