    I have listened to several episodes and I eventually plan to listen to ALL of the episodes. The ones I have caught so far have been chock-full of useful information (I wish I had this resource years ago). I’m guilty of having a disorganized raw material sample shelf, but after listening to this episode I have pledged to get organized once and for all using your system. Thanks for the help!

    Hi Perry,
    I wanted to double check if the spreadsheet supplied for this day is the correct spreadsheet. It looks to be a cost saving spreadsheet and the same supplied on the next days podcast. If there’s another spreadsheet example you’ve used and you’re open to sharing it, I’d love to see it.
