I do Store>Designer>Kit. I also keep a spreadsheet with the designer name, kit name, store purchased at, then additional stores if they are at others (I have 4 columns right now), then I have categories the kit can fall into that I just put and X in - things like Seasonal, Heritage, Children, Artsy, etc. I also have a column for "Freebie" and "not in store" for those kits that are retired. I'm happy to share if anyone wants to see it. I work with spreadsheets all day, every day at my day job. They are my sanity and life savers!
