I was asked to start this thread due to people finding the new Itemized Order History on the new DAZ site a cumbersome tool. Someone suggested a spreadsheet, and I decided to try it. It helps me keep my sanity, and I suggested it to others. They in turn asked for a little tutorial as a PDF offered here, so others can find it later.

I gave this thread a general name hoping other tutorials will find their way here, as well.
