I'm not saying he's scamming, but it's pretty darn likely.
He is offering amazon giftcards @13000 $ per bitcoin, with no cash receipt, (so digital only?) and has -24 ratings.

Add these things up and you have a cocktail filled with immense risk.

I'd avoid him as the only way he can sell Amazon giftcards that cheap is by either fucking someone else over (hacking, etc.), or he's carding them/using them to launder other money.
(or the obvious: he's just scamming.)

Note: he also has +700 ratings, but, i've been a paxful seller, and it was really, really trivial to boost your account/ratings. there were entire groups of people () boosting each other into thousands of reps.

Also his ID verification is really no indication of his trustworthiness. It could be a photoshopped one, or if he's from a third world country he could've simply bought it for a few hundred bucks.

TLDR: If it seems too good be true....
