Affiliate disclosure

The fix list links to Amazon searches for the exact item each gap names. We may earn a commission on qualifying purchases made through those links, at no extra cost to you.

The links carry only the item's search terms. They carry nothing about you: not your answers, not your score, not your city.

Items are on the list because they close a gap in your answers, not because of what they pay. The score is the same whether you buy anything or not.
