Here's a couple things that might apply
- you might have two cornucopias from thanksgiving, I have two from separate years
- so sorry but there's a typo, first ever christmas tree is 0.25
- if you bought five alarm chilli in the chilli cook off it's 2.5%
- don't you get 5% from conformometer? ie 1% for each star you fill in the top instead of sub items?
- festive light plunger increased this winter to 2.25%
