i understand but by refusing escrow people start thinking i am a scammer ,
i don't mind use it with accounts ( i can change passwords later)
but the voucher is a bit problem
This the downside on selling vouchers. Your buyer might reject payment by claiming he didn’t use the voucher. I think you can solve this if there’s a way which escrow can test the vouchers before he can handle it to the buyer. This way both party can assure that the product is working since the middle man checks it first.
Bitcointalk trusted escrows are smart on handling deals like this but their might be high compared to your voucher price.
