Feedback seems fake. 10 orders all seem to be from the same buyer account. Vendor account was made 1 day ago, yet one of his feedbacks says shipping took four days... I can't say for sure that he is scamming, but it is a bit sketchy. I would avoid if possible.
Thanks for posting! You have got to be right. I'd let Support know if you haven't already. I bet you caught this before he got a chance to scam anyone and that is awesome.
