I don't understand the eBay standard envelope method

[thingsinherited]

Greetings, I am the designated dummy of the day.  I got the eBay message today about the eBay standard envelope option.

  I use templates for my descriptions. Can I add this method to my shipping policy list and if so how do I do it? 

  Can I use standard 6" x 8" semi rigid mailers with this option? I have lots of postcards and ball cards. I understand the limits on weight and number of items per sale.

  If I make a sale under $20 and under 2 oz will the label print with the standard envelope rate? 

Thanks for any clarification you can help me with.

Thanks, I think I got it figured out. Had a heck of a time getting my template changed.

Your rigid mailers may be way too rigid for using the eBay Standard Envelope.  The envelope must be flexible enough to swiftly slip through the USPS sorting machines -- if they are too rigid, the machines will reject them, and they'll be reclassified as USPS First Class Packages, at a higher rate (over $3.00 each).

Check with your post office regarding the flexibility of those rigid mailers before you start using them for the ESE.
