Having just emptied my winter food box late November 16, and finding an extra 7 items in there, I have decided to do it again for winter 2016/2017 food box:
December 3rd 2016 is the start date for this next box and so far, it has:
Mushrooms x 2
Manderins x 2
That means I don't have to start filling it until January 20th 2017 - not a bad start.
