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.
Harold
