I worry about international shipping so i stay away from it as much as possible. But you just pointed something out that i never figured into the equation. Mainly the flat rate envelopes and boxes, and insurance. I wonder if my international buyers are willing to absorb these cost for my original abstract prints.
Visit my ebay store Urban Picasso Art. Were I ship Internationally Thanks to auctiva.
