<p>That would be a good idea, but I don’t have the time, nor do I want to spend $100 to send a package. I was going to send them in a Fedex letter envelope so that they will arrive in 2 days. If I send a book, it would be another package, and it isn’t cheap. Plus, if they go through the book there is no telling what would happen with the credit card.</p>
<p>I was going to tape all to a piece of paper and then put other papers on both sides so that you would not be able to feel the cards through the cardboard envelope. I guess I could put a magazine in the envelope and then tape the cards in the magazine. I would not think customs would open a Fedex (or UPS/DHL) letter envelope, but you never know.</p>
