This is a simple guide for sending PWEs or plain white envelope trades. I will also be including other methods of sending flat items, such as photo mailers, in the future.
​
There are many ways of sending lower value cards but this is the method that I use. I wouldn't suggest mailing more than 10 cards per envelope, because the USPS will only accept a certain thickness. An envelope that is too thick, then becomes a package, which now costs $3.50. If the envelope you are sending is less than an ounce, which it normally is, the cost is $0.71. ($0.50 + $0.21 surcharge)
PWE (Plain White Envelope) - Method 1
1. Cut out 2 pieces of light cardboard, just a bit smaller than a business sized envelope. I use cereal boxes for this purpose, but any similar cardboard will do. For this demonstration, I will be using an Ellio's pizza box. (Bonus: The cards will have a delightful sausage scent)
2. Place your cards into penny sleeves and then into two team bags. You can also wrap them carefully in a small piece of paper or a sandwich baggie if you haven't got any on hand.
3. Now, tape the team bags to one side of your cardboard. Painters tape is recommended because it peels off easily and doesn't leave behind sticky residue.
4. Tape the other side of your cardboard to the one your cards are attached to. You've created a sandwich! (Disclaimer: DO NOT EAT!)
5. The most important part of this process is mailing the cards. You do not want to just stick a couple of stamps on the envelope and toss it in a mailbox. You must physically bring it into the post office and tell them you want your parcel sent as a "non-machinable" item. Your item will then be put in a separate bin, that will not be subject to the mailing machines that a traditional envelope would pass through. Those machines really can damage the cards. As stated before, there is a surcharge to send a non-machinable item, but it will be worth it when your cards arrive in the condition they were sent.
PWE (Plain White Envelope) - Method 2
Here's a method similar to the first one. My trade partner has used a card page, cut into three panels. Each card had a small piece of blue painters tape at the top, to keep the card from popping out. This again was under an ounce, so it cost him only $0.71 to send.

Again, this was mailed properly, by bringing it into the post office and having it sent as a non-machinable item.
