Paid by Paypal with their goods and services system. If I don't get them i'll let paypal know and get the money back.
Edit: Also, I didn't send him $350, I payed for $350 worth of GC's.
Oh, if you paid by PayPal you're all good. He most likely did scam you but you can always chargeback it.
That doesn't matter.
You think? He can easily transfer the funds to his other PayPal account or better yet exchange those with Bitcoin Exchangers so good luck getting back your money.
