About Shipping and Handling: All postcards are enclosed in protective sleeves. Postcards are mailed First Class. Tracking is now required by eBay, which is why shipping is now over $2 -- tracking requires that even postcards be shipped as a first class PACKAGE -- which is far more expensive than simply mailing as a first class letter.  I package with cardstock or heavier weight paper protecting both sides of the card. I am happy to combine shipping if you buy more than one item from me. Please ask for adjusted shipping amount before payment. If you don't ask before payment, I will refund part of the shipping cost to your PayPal account. Normally you will only pay shipping for the first card. 

My shipping charge includes a small handling and packing materials charge, which covers the cost of the packaging and transportation to a post office. I try to use recycled materials for packaging as practical and possible, but there are going to be some costs involved with packaging.

About Feedback: I always post positive feedback and I appreciate your positive feedback in return. If you have any problems at all with your purchase, please contact me so that we can resolve the issue!

NOTE: Tracking is not available for INTERNATIONAL shipments. These will continue to be sent via International First Class mail.
