I use the United States Postal service. I use priority mail and a tracking number. Regular paintings are 15.00 and smaller paintings are 9.00 I ship your painting when I am paid. Pay Pal orders go out each day. Money order payment have to clear 3 days. I try to show enough photos of my art so you can see. But, monitors are different from computer to computer. I accept returns with a valid reason. Postage is not refundable. I must have the art work returned to qualify for a refund.
