Experience with ebay seller Brandoff?

Jan 2, 2017
This seller has a purse that I like. I asked for more pictures and they said that the bag is in Asia, so they wouldn't be able to send pics until it was ordered and shipped to their offices here. They said that if I want to cancel my order at that point, then I could & that they guarantee authenticity.

I normally wouldn't even consider it but, if I remember correctly, several people listed them as a suggested seller. The purse is in good condition, I have enough pictures to know that.. I'm just questioning authenticity. Would I be completely insane to pay with paypal & then just dispute the charge if it turns out to be fake?
