i have dealt with Saffron art, not once but about 4 times, I have also participated in their online auction. They will send the paintings bought on their website, they charge you for shipping and insurance. but most of the paitings come in good framing, with an aunthenticity report with it. I like them and will use them again if need be.
I have had no experience with them, but by reading about them and hearing from other artists I have the impression that they are snobbish and are promoting snob appeal.
