Reasonable shipping charges for multiple item shipments. To protect the cards, I ship in a padded bubble mailer. I do not ship in a "plain white envelope." Within the USA my shipping charge is $3.75. I add $0.10 for each additional card. A tracking number will be provided. (To Canada: I charge $9.75 plus $0.10 for each additional card. To all other countries: I charge $13.80 plus $0.10 for each additional card.) I strive to post shipment within 1 business day of payment. Whenever possible I will bundle a buyer's multiple purchases into 1 package.
