Special editions
Xmas editions, summer specials, special interests - all possible!
If you're creating a special edition that's outside the normal schedule that you have established with Amazon Newsstand, you can fetch a custom feed URL just for that special edition.
In the top right corner of every issue you’ll see a small RSS icon 
You can then email this link to [email protected] in good time (allow up to 12hrs typically) and they will create and distribute the special edition for you. Do instruct them clearly that this is a special edition and the usual link should continue.
