Camera purchase from eCrate...is it real?

[krakensurf]

I want to buy this camera

http://ritrexcamera.ecrater.com/p/28482457/panasonic-lumix-dc-gh5-mirrorless

but I can't determine if this guy is a real offer or a scammer.  I've contacted the seller, and he responds to questions.  What should I ask to determine if this guy isn't just some con-artist?

Thanks
