Hello! At my Purchases spreadsheet https://docs.google.com/spreadsheet/ccc?key=0AmY3HgUDDM9kdEs1Tzg0cE92T2x3MEtwX0NrQk9pR2c - can anybody recommend a way of calculating when it's time to get more packaging material and photographs - and how to best model this in my spreadsheet?
Thank y'all so much!
Mikkel
P.S. Anyone can edit this document.
