Free super saver delivery alternatives - how to add content 

Hi. You deleted the "Free super saver delivery alternatives" page I created yesterday. I thought it had enough context (it talked about Amazon's free super saver delivery system, when it ended and listed the current alternatives in the European market), but apparently more context was needed.
I am willing to edit the page and add more information (the whole idea was that other people could contribute as well), but it has been deleted and I cannot pick up where it was left off.

How can one retrieve the previous version and complete it?
