One of the problems with
Amazon is that there's no way to tell what kind of items the individual Feedback comments refer to. Also there's no way to tell if the seller takes their own photos, and there's no description at all of the bag, not even whether or not it's NWT or NWOT and if the bag in the photos is the exact one you'll receive. Remember, you're not buying from
Amazon, you're buying from a private seller.
So to answer your question - do
you see anything at all that tells you they're reputable? Because I don't. Maybe they are, but if I'm thinking of spending 300 bucks I want a lot more proof than just some photos that may or may not be the bag I'm buying.
Personally the only way I'd buy from a private seller on Amazon is if I knew and trusted the seller from another site. JMO.
