She said if the cards themselves and the envelopes that comes with them could make the difference in prices. When I got home I checked all my cards and envelopes from the Dollar Tree and found they are different thickness. Lesson learned.
The Post office has a template with a "slot" in it. The PO clerk "drops" your letter through the slot as a test. (the test is it must be thinner than 1/4") If it drops through easily, and doesn't get hung or stuck, you pass and your charge is $0.71. Here is a picture of the template.

It is made of hard plastics so it stays stable as you drop your letter through. You can ask your post office how to get one of these templates. The other "machinable" characteristic you have to have is flexibility. So don't put a rigid piece of cardboard in your letter, like we use to do to send photos!
