I keep a Word document too but I have it in ABC order by the name of the scent. With a scent like all of the vanillas, I list vanilla,ultimate or vanilla,velvet, etc. I put the suppliers too. Then I make a short note of OOB opinion. I keep my notes of how it performed in a product in a notebook but someday I might get ambitious & add those notes to the Word document. If I didn't have that document I'd have duplicate scents too!! I also keep lists of scents I want to try from different suppliers-you know how you want to feed the addiction so you go and fill a shopping cart but you can't afford it so you just make a wish list!LOL
