40$ is very high for this, its well above 10% service fee, and we should use escrow, choose any respected escrow here, or you go first.
Thanks
40$ is
very high for you?
The gig costs 35, so one makes just $5
To spend the btc he has to spend around $2
So one gets around mere $3 and you think it is very high
Be practical man. respect other's time and effort.
