Tom,
After buying extra parts as you mentioned in your post, I taught myself how to use the Excell spreadsheet. Now I list the date purchased, Description, P/N, supplier, price inc tax and shipping and location (were I placed the part until needed) Once I use the the part, I replace the location with Installed.
I can tell at a glance where the parts are and the TOTAL price of what I have purchased.
It takes a few minutes to set up but the end result pays off "BIG TIME" in knowing where your parts are and preventing duplicate buys. It is also a "road map" of what is left to do to complete the project.

And the wife doesn't have the password to the spreadsheet to find out what you REALLY spent on the project.
Was my nightmare for me personally.
