What’s so strange about buying a Picasso at Costco? They have an excellent return policy. “By visiting costco.com and searching under ‘fine art,’ buyers can access a list of artworks for sale by Marc Chagall, Amadeo Modigliani, Henri Matisse, Georges Braque and others. On Wednesday, prices on the ever-changing list ranged from $21.49 to about $1,500, for a limited-edition lithograph. With a click of the mouse, you can add art to your cart.”
