a few things gave him away..but I will list 2 for now:

1) cheap because of buying wholesale and so on. That is NOT POSSIBLE because PS4 is controlled price item. Sony is not that stupid to allow resellers to undercut the PS4 prices if they go through the proper distribution channel. It they are using underground channel then it means the item is not proper. Meaning could be stolen items or inferior quality or no warranty and so on.

2) 12 hour delivery?? Are you crazy? Even DHL or UPS cannot provide this kind of service. Their 1 day express delivery is how much, you know or not? And he does not charge on that? Definitely scam!!
