Things we track on the same shelf for at least 10% less than $44.99, with the attributes the retailers describe differently. Their words, not our judgement: we record prices, we do not test products.

Every change we recorded at Amazon

Every row is a price we saw change. We write one only when a price actually moves, so a gap here means the price held.
