I sell framed prints locally in a gallery, and online. I absolutely get that people don’t want to invest in a print they haven’t seen in person - which is why most of my online sales come from people who’ve been to the gallery.
Would you be more inclined to purchase art online if it came with an “it doesn’t match my sofa” return policy? No one has complained or asked for a refund or replacement yet, and of course I would take art back if someone didn’t like the image once they received it.
But if I specifically advertise doing that, will people buy my images, use them for open houses, and then return them like a soiled party dress? I have little faith in the masses.
