and reason for giving $50 discount is only for trusting me
That's a classic scammer line offering a discount if they just trust you. There's nothing to stop you from running off with the money once you get it. Use escrow and provide proofs and you'll be fine, or only sell to someone fairly trusted.
i done deal with ryuga and remmber all are not scammers and i even answered for gicing discount i.e since 1month as no one came forward i offered for such low and stop criticising me when i not done anything wrong and if i did naything bad with you you can claim,ok.
