IMO the subject of FE should have been brought up sooner. To have your order cancelled thus incurring you a loss is very unfortunate, whether that constitutes a scam attempt or not I will leave up to the admins to decide given you have reported the vendor already, my opinion in this matter is irrelevant given nothing can be done from here beyond discussing what happened and individuals offering their subjection opinion. I should point out though it is not against the rules for an established vendor to ask for a buyer to FE by the way and doing so does not necessarily make them a scammer.
